ansible-playbook site.yml -i inventory.ini -v
```
### Run Specific Phase (if earlier phase fails)
```bash
# Re-run only Phase 3 (filesystems)
ansible-playbook site.yml -i inventory.ini --tags phase-3
# Or specific phase
ansible-playbook site.yml -i inventory.ini --tags phase-4
```
### Check Mode (show what would change)
```bash
ansible-playbook site.yml -i inventory.ini --check
```

## Variables (group_vars/bigboy.yml)
All hardware-specific settings live in one place:
```yaml
# NVMe UUIDs
uuid_nvme_root: "5daac1d7-10b3-498a-82b0-a4498d7e0717"
# Data drive UUIDs
uuid_rag_library: "18b9accd-754a-46f3-b994-da3c7ae795cd"
uuid_prompt_library: "82a240c4-390a-4167-8232-6a04ce4d84bb"
uuid_backup: "15b69400-f1f7-4cfd-82cb-4d1244951503"
uuid_ai_logs: "1e57a52a-9c9d-44ef-a352-3cc542808d13"
# GPU settings
nvidia_driver_version: "595.84"
cuda_visible_devices: "0"
# Ollama tuning
ollama_max_loaded_models: 1
ollama_keep_alive: "5m"
ollama_gpu_overhead: 536870912 # 512MB
```
**To update:** Edit `group_vars/bigboy.yml`, then re-run playbook. Variables propagate to all roles.
---
## Idempotency
Every task is idempotent (safe to re-run):
- Mounts already present = no change
- Packages already installed = no change
- Services already running = no change
- Shell commands wrapped with `changed_when` to report accurately
**Key principle:** Running the playbook twice produces the same result as running it once.
---
## Logging
All output is logged to `/srv/deployment-log/` on BigBoy:
```
/srv/deployment-log/
├── phase-03-filesystems-2026-06-27.log
├── phase-04-nvidia-driver-2026-06-27.log
├── phase-05-ollama-2026-06-27.log
└── ... (one per phase)
```
Each log includes:
- Timestamp of each task
- Module output
- Failure diagnosis (if applicable)
**To view:** `ssh root@192.168.0.240 "tail -f /srv/deployment-log/*.log"`
---
## Troubleshooting
### Phase fails mid-run
1. Check the specific phase log: `tail /srv/deployment-log/phase-N-*.log`
2. Fix the issue manually if needed
3. Re-run the phase: `ansible-playbook site.yml --tags phase-N`
### SSH connection fails
1. Verify BigBoy IP: `ssh -v root@192.168.0.240`
2. Check SSH key permissions: `chmod 600 ~/.ssh/id_rsa`
3. Ensure root SSH login is enabled on BigBoy
### Idempotency broken (task reports change every time)
- Check `changed_when` / `failed_when` directives
- Verify the conditional logic
- Use `-vv` for detailed task output
---
## Extending (Adding Phases)
To add Phase 4 (NVIDIA driver):
1. Create directory:
```bash
mkdir -p roles/phase-4-nvidia-driver/tasks
```
2. Create `tasks/main.yml` with steps (use alma-nvidia-driver-installation.txt as reference)
3. Add role to `site.yml`:
```yaml
- role: phase-4-nvidia-driver
tags: [phase-4, gpu, nvidia]
```
4. Run playbook:
```bash
ansible-playbook site.yml --tags phase-4
```
**Pattern:** Each phase = one role = idempotent, re-runnable, logged.
---
## SSH Key Setup (Post-Install)
BigBoy ships with password authentication. To switch to key-based:
```bash
# 1. On Workbench, generate key (if not already done)
ssh-keygen -t ed25519 -f ~/.ssh/id_rsa -N ""
# 2. Copy key to BigBoy (will be automated in Phase 9)
ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.0.240
# 3. Verify key auth works
ssh -i ~/.ssh/id_rsa root@192.168.0.240 "echo 'Connected'"
# 4. Phase 9 will disable password auth once keys are in place
```
---
## Validation Checklist (Post-Deployment)
After all phases complete:
```bash
# SSH to BigBoy
ssh root@192.168.0.240
# Check filesystems
df -h /srv/*
# Check GPU
nvidia-smi
# Check Ollama
ollama --version
systemctl status ollama
# Check services
systemctl status firewalld
systemctl status sshd
# Check logs
tail -f /srv/deployment-log/*.log
```
---
## RAG Integration
All phase logs are automatically captured to `/srv/deployment-log/` and ready for RAG indexing:
- Workbench cron harvests logs nightly
- Failures documented (not just successes)
- Workarounds captured for future reference
---
## Known Limitations / Deferred
- **Phase 10 (Borgmatic):** Backup target not yet decided; packages installed, schedule deferred
- **Phase 13 (Home LAN):** Deferred until Modcase EVO ITX-2 case installed and system is cased
- **Phase 14 (Observation):** Runbook template only; manual health checks during first month
---
## Reference Files
- `alma10-minimal-bigboy.ks` — Kickstart for unattended OS install
- `/home/john/documents/library/rag/use-case/ansible-*.md` — Ansible best practices, modules, error handling
- `/home/john/documents/raw-docs/alma-nvidia-driver-installation.txt` — Official NVIDIA guide (reference)
---
## Support / Issues
- **Logs:** Check `/srv/deployment-log/phase-N-*.log` first
- **Ansible:** Run with `-vvv` for full debug output
- **Hardware:** Verify UUIDs in `group_vars/bigboy.yml` match actual system
---
**Last Updated:** 2026-06-27
**Status:** Phase 3 complete and tested; scaffolding ready for Phases 4-14

# BigBoy AlmaLinux 10 Architecture
**Design rationale, system architecture, 14-phase deployment strategy**
---
## Design Philosophy
### Core Principle: Pragmatism > Complexity
BigBoy prioritizes:
1. **Reproducibility** — Every deployment step logged and idempotent
2. **Maintainability** — Clear, documented decisions; no exotic tooling
3. **Stability** — RHEL-compatible base; 10-year support lifecycle
4. **Simplicity** — Ansible (battle-tested) over NixOS (novel configuration)
**Why AlmaLinux 10 over NixOS?**
- NixOS attempt (earlier in project) encountered feedback loop problems: no error visibility → false negatives on GPU driver compilation
- AlmaLinux 10 offers: official NVIDIA precompiled drivers, standard package management (DNF), proven RHEL ecosystem, clearer error messages
- Trade-off accepted: less declarative (Ansible > Nix) but faster iteration and debugging
---
## System Architecture
### Hardware Context
| Component | Spec | Impact |
|-----------|------|--------|
| **CPU** | Intel/AMD (not specified) | Sufficient for 4GB model inference + Ollama service overhead |
| **GPU** | RTX 5060 Ti (4GB VRAM) | Limits model size (~4GB quantized models like mistral:7b) |
| **RAM** | 16GB system | Comfortable for OS + Ollama + Open WebUI + vector DB |
| **Storage** | 5 drives, btrfs | NVMe (OS), 4× SATA (data isolation) |
| **Network** | Fritzy bench LAN | 192.168.0.240 on 192.168.0.0/24 |
### Filesystem Architecture
```
NVMe (500GB btrfs)
├── @ (mounted as /) — OS + system
├── @home (mounted as /home) — User data
├── @nix (mounted as /nix) — (unused, legacy from NixOS planning)
└── @log (mounted as /var/log) — Logs (zstd:1 for fast writes)
SATA Drive 1 (btrfs)
└── @rag-library → /srv/rag-library
SATA Drive 2 (btrfs)
└── @prompt-library → /srv/prompt-library
SATA Drive 3 (btrfs)
└── @backup → /srv/backup
SATA Drive 4 (btrfs)
└── @ai-logs → /srv/ai-logs
```
**Design rationale:**
- Subvolumes (not LVM) for CoW snapshots, compression, efficient backups
- Separate SATA drives avoid single-point failure cascading
- zstd compression (level 3 general, level 1 for log-heavy subvolumes)
- `nofail` mount option on SATA drives (one failure ≠ system down)
### Service Architecture
```
Layer 1: OS (AlmaLinux 10.2 minimal)
├─ Kernel (6.12+)
├─ Systemd (service management)
└─ DNF (package management)
Layer 2: Runtime
├─ NVIDIA driver (precompiled open kernel modules)
├─ CUDA libraries (via nvidia-driver-cuda package)
└─ SSH (for Ansible execution)
Layer 3: Inference
├─ Ollama (model server on :11434)
└─ GPU acceleration (CUDA, RTX 5060 Ti)
Layer 4: Interface (Optional)
└─ Open WebUI (web interface on :8080)
```
---
## 14-Phase Deployment Strategy
Each phase is:
- **Idempotent** — Safe to re-run
- **Logged** — Output captured to `/srv/deployment-log/`
- **Tagged** — Runnable in isolation with `--tags phase-N`
- **Isolated** — One role per phase, minimal cross-phase dependencies
### Phase 3: Filesystem Validation ✓ (Complete)
**Goal:** Mount all 4 data drives, validate btrfs structure, report space.
**Input:** Kickstart-created NVMe filesystem + raw SATA drives
**Output:** 4 mounted subvolumes at `/srv/*`, logs in `/srv/deployment-log/`
**Status:** Complete, tested, idempotent
### Phase 4: NVIDIA GPU Driver 🔨 (Ready to Build)
**Goal:** Install NVIDIA RTX 5060 Ti driver, verify CUDA availability.
**Method:** Precompiled open kernel modules (AlmaLinux-provided, no compilation)
**Packages:**
- `almalinux-release-nvidia-driver` (enables repos)
- `nvidia-open-kmod`, `nvidia-driver`, `nvidia-driver-cuda`
**Verification:** `nvidia-smi` shows RTX 5060 Ti, CUDA version, GPU memory
**Dependencies:** Phase 3 (filesystems ready)
### Phase 5: Ollama Installation 🔨 (Ready to Build)
**Goal:** Install Ollama model server, configure for RTX 5060 Ti VRAM limits.
**Method:** Official installer script + systemd service
**Configuration:**
- `CUDA_VISIBLE_DEVICES=0` (single GPU)
- `OLLAMA_KEEP_ALIVE=5m` (keep model in VRAM 5 minutes)
- `OLLAMA_NUM_PARALLEL=1` (single concurrent request for 4GB VRAM)
- `OLLAMA_GPU_MEMORY_PERCENT=90` (use 90% of 4GB)
**Model pull:** `mistral:7b` (recommended for 4GB VRAM)
**Verification:** `ollama ls` shows model, API responds at `http://localhost:11434/api/tags`
**Dependencies:** Phase 4 (GPU driver ready)
### Phase 6: Build Suite
**Goal:** Install development tools (gcc, make, git, tmux, vim), system utilities (btrfs-progs, smartmontools, nvtop).
**Packages:** `@Development Tools` group, kernel-headers, kernel-devel
**Purpose:** Support future customization, debugging, model fine-tuning
### Phase 7: Configuration
**Goal:** Deploy dotfiles (tmux.conf, vimrc, bash profile), set locale/timezone.
**Artifacts:** Dotfiles from `/home/john/projects/` or CE OS defaults
**Outcome:** Standard development environment
### Phase 8: Open WebUI (Optional)
**Goal:** Install web interface for Ollama models (optional enhancement to Phase 5).
**Method:** Python pip installation + systemd service
**Configuration:**
- `OLLAMA_BASE_URL=http://localhost:11434` (local Ollama)
- Port 8080, accessible from Fritzy bench LAN
- First user becomes admin
**Purpose:** User-friendly chat interface; RAG/knowledge base support
### Phase 9: Security Hardening
**Goal:** Lock down system for LAN deployment.
**Tasks:**
- Firewall (firewalld): SSH 22, Open WebUI 8080, Cockpit 9090; Ollama 11434 localhost-only
- SSH hardening: Disable password auth, PermitRootLogin=no (after key setup)
- MAC address pinning for consistent network identity
- SELinux review (AlmaLinux default: enforcing)
### Phase 10: Borgmatic Backups
**Goal:** Automated encrypted backups to external storage.
**Status:** Deferred (backup target not yet decided)
**When ready:**
- Install borgbackup + borgmatic
- Configure retention policy
- Schedule nightly runs
- Test restore procedure
### Phase 11: Thermal Baseline Testing
**Goal:** Establish safe operating temps under load.
**Tests:**
- Memtest86 for CPU/RAM stability
- Ollama inference with large model
- Log CPU/GPU temps, fan speed, power draw
- Record baseline performance
**Outcome:** Confidence in cooling system, safe turbo limits
### Phase 12: Full System Validation
**Goal:** End-to-end test of all 11 prior phases.
**Validation:**
- All services running (Ollama, Open WebUI, SSH, Firewall)
- GPU utilization verified
- Storage health checked
- Network connectivity verified
- Logs reviewed for errors
**Report:** Consolidated validation status
### Phase 13: Home LAN Migration
**Status:** Deferred (waiting for ITX-2 case installation)
**When triggered:**
- Static IP assignment (192.168.0.240)
- DNS configuration (if needed)
- Network documentation update
- Bench → home transition runbook
### Phase 14: Observation Period Runbook
**Goal:** Daily/weekly health checks during first month of operation.
**Routine:**
- Monitor temps (should stay <70°C GPU, <60°C CPU under inference)
- Check disk usage (compression ratio, growth rate)
- Verify service status (systemctl status ollama open-webui)
- Monitor logs for errors/warnings
- Document any issues, anomalies
**Duration:** 4 weeks post-deployment
---
## Technology Choices & Rationale
### OS: AlmaLinux 10 (not NixOS)
**Decision:** Pivot from NixOS after encountering feedback loop problems.
**Why:**
- NixOS benefits: declarative, reproducible, atomic deployments
- NixOS costs: complex error messages, NVIDIA driver compilation failures lacked visibility, iterative debugging slow
- AlmaLinux benefits: standard RHEL ecosystem, NVIDIA precompiled drivers, clear error messages, battle-tested
- AlmaLinux costs: imperative (Ansible), slightly less declarative
**Trade-off:** Lost declarative elegance for faster iteration and debugging. Pragmatic for single-system deployment.
### GPU Drivers: Precompiled Modules (not DKMS)
**Decision:** Use AlmaLinux-provided precompiled open kernel modules.
**Why:**
- No compilation (DKMS would require gcc, kernel-devel, takes 10-15 min per kernel update)
- Secure Boot compatible (modules signed by AlmaLinux)
- Simpler dependencies
- Proven on AlmaLinux 9/10
**Alternative:** DKMS method available if precompiled unavailable for new kernels
### Model Server: Ollama (not vLLM, not llama.cpp)
**Decision:** Ollama as primary inference server.
**Why:**
- Simplest setup (one-line install, systemd service)
- GPU-optimized (CUDA, AMD ROCm support built-in)
- Model management (pull, ls, rm commands)
- REST API (OpenAI-compatible)
- Community support
**Optional:** Open WebUI as web interface layer
### Filesystem: btrfs (not ext4+LVM)
**Decision:** btrfs subvolumes for NVMe and SATA drives.
**Why:**
- CoW snapshots (space-efficient point-in-time backups)
- Built-in compression (zstd: 30-40% space savings typical)
- Subvolume isolation (one drive failure doesn't cascade)
- No repartitioning needed to add subvolumes
- Online filesystem expansion
- kABI guarantees for kernel module stability
**Trade-off:** Slightly slower on small random I/O vs. ext4; negligible for this workload
### Deployment: Ansible (not Terraform, Puppet, Chef)
**Decision:** Ansible for 14-phase orchestration.
**Why:**
- Agentless (SSH only)
- YAML playbooks (readable, versioned)
- Idempotency built-in (safe re-runs)
- No learning curve (familiar to Linux admins)
- Excellent module library (dnf, systemd, mount, file, shell)
**Deferred:** Terraform would shine for multi-server infrastructure; overkill for single BigBoy
---
## Monitoring & Observability Strategy
### During Deployment
- Each phase logs to `/srv/deployment-log/phase-N-YYYY-MM-DD.log`
- Logs harvested nightly to `/home/john/documents/library/rag/sessions/` for RAG corpus
- Failures captured (not just successes) for troubleshooting reference
### During Operation (Phase 14 onward)
- `nvidia-smi` for GPU health (temp, utilization, VRAM)
- `systemctl status ollama open-webui` for service status
- `journalctl -u ollama -f` for runtime errors
- `btrfs filesystem usage /` for storage health
- Thermal baseline established during Phase 11
### Alerting (Future)
- Email alerts on service failure
- Temp threshold warnings (>75°C GPU)
- Disk usage warnings (>90% full)
---
## Disaster Recovery Strategy
### Filesystem Backups
- btrfs snapshots (local, instant, CoW)
- Borgmatic to external storage (Phase 10, when target decided)
- 3-2-1 rule: 3 copies, 2 media types, 1 offsite
### Service Recovery
- All phases idempotent → can re-run Phase 5 to recover Ollama
- Systemd service auto-restart on failure
- Logs captured for root cause analysis
### GPU Driver Issues
- Precompiled modules = no kernel compatibility surprises
- Fallback to CPU-only (set `CUDA_VISIBLE_DEVICES=-1`)
- DKMS method available if needed
---
## Growth Path (Beyond 14 Phases)
**BigBoy as foundation for:**
1. **Fleet deployment** — Replicate to other machines (Ambrosiana, fivealive)
2. **Multi-model serving** — Load balance across RTX 5060 Ti + future GPUs
3. **Fine-tuning infrastructure** — Training compute (when available)
4. **Distributed RAG** — Ollama embeddings + vector DB scaling
5. **Agent orchestration** — Autonomous workflows across CE OS fleet
---
## Known Limitations & Future Work
### Current (Q3 2026)
- Single GPU (RTX 5060 Ti) = models limited to ~4GB
- Single concurrent request (OLLAMA_NUM_PARALLEL=1)
- No distributed inference (single-machine only)
- Borgmatic backup deferred (target TBD)
### Future Opportunities
- Multi-GPU scaling (if second RTX added)
- Quantization exploration (GGUF variants)
- Prompt caching (for repeated contexts)
- Speculative decoding (speed up inference)
- Custom Ollama forks (if needed for specific workloads)

# Storage space by subvolume
du -sh /srv/rag-library /srv/prompt-library /srv/backup /srv/ai-logs
# GPU health
nvidia-smi -q | grep -E "Temperature|Power Draw|VRAM"
# Compression effectiveness
btrfs filesystem usage / | grep "Unallocated"
```
### Quarterly Actions
```bash
# Scrub btrfs (check for corruption)
sudo btrfs scrub start /
# Check SMART health
sudo smartctl -H /dev/sda /dev/sdb /dev/sdc /dev/sdd
# Defragment if needed (rare for zstd)
sudo btrfs filesystem defragment -v /srv/rag-library
```
### Annual Review
- Update kernel
- Review thermal baseline (compare to Phase 11 baseline)
- Review backup strategy (if Borgmatic in use)
- Consider GPU driver update (if new version available)
---
## Hardware Upgrade Path
### GPU Addition (If VRAM Bottleneck)
- Slot: PCIe 4.0 x16 (secondary)
- Candidate: RTX 4070 Ti (12GB) or RTX 4090 (24GB)
- Ollama config: Set `CUDA_VISIBLE_DEVICES=0,1`
- Load balancing: Requires model routing logic
### Storage Addition
- NVMe: Add 2nd NVMe via M.2 slot (if available)
- SATA: Cascade to eSATA or USB 3.0 (slower, external)
- btrfs: Add device: `sudo btrfs device add /dev/new /mount/point`
### RAM Upgrade
- If Ollama uses >12GB: Add DIMM
- Typical: 16GB is comfortable for 4GB GPU model serving
---
## Compliance & Documentation
### For Disaster Recovery
- Keep copy of this HARDWARE.md in `/srv/backup/`
- Include UUID list in Phase 14 observation runbook
- Document MAC address pinning decision (Phase 9)
### For Audit Trail
- All hardware changes logged to `/srv/deployment-log/`
- Kernel version tracked by systemd logs
- NVIDIA driver version in `nvidia-smi` output, logged during Phase 4

# CE EU AI-Cloud Sovereignty Policy — Handoff for Claude Code
**Version:** 1.0
**Date:** 2026-06-27
**Scope:** Cervello Elettrico (CE) commitment to EU AI and Cloud sovereignty through voluntary regulatory contribution
**For:** Claude Code @workbench — all infrastructure, deployment, and documentation work
---
## I. CORE COMMITMENT
CE operates under a **community service mandate** to strengthen EU AI-Cloud sovereignty. This is not a marketing position or regulatory compliance checkbox. It is a **foundational design principle** that shapes every system we build.
**Core Statement:**
> We are not vendors trying to minimize compliance cost. We are practitioner-researchers demonstrating how local AI, privacy-first infrastructure, and sovereign computing serve EU citizens and SMEs. Every technical decision is made with the knowledge that it will inform EU policy and provide evidence for better regulation.
**Practical meaning:** Contribution is **built into systems**, not taped on post-deployment.
---
## II. THE POLICY FRAMEWORK
### A. Three Commitments
1. **Letter AND Spirit of Regulation**
- Exceed minimum compliance
- Anticipate stricter future requirements
- Log more than legally required today
2. **Forward-Thinking Compliance**
- Build for the regulation coming, not just the one we have
- Establish audit trails now (years of history before auditors ask)
- Design flexibility to adapt to unknown future rules
3. **Voluntary Contribution to EU Policymakers**
- Submit evidence and recommendations to EU Commission
- Publish findings (Codeberg/public repos)
- Participate in stakeholder consultations
- Build regulatory-ready documentation at each phase
### B. Guiding Principle: Sovereignty ≠ Isolation
Local AI deployment means:
- **Private by design** (data stays on-premises or Aruba/EU only)
- **Transparent by design** (full audit trail, nothing hidden)
- **Auditable by design** (regulators can inspect exactly how it works)
- **Economically viable** (SME-affordable, not enterprise-only)
---
## III. TECHNICAL ARCHITECTURE FOR CONTRIBUTION
### A. Logging Standard (Exceeds Legal Minimum)
All deployments must use this logging structure. Logs are designed to answer regulatory questions, not just operational ones.
#### Inference Logging (`/srv/ai-logs/inference/`)
**Format:** JSONL (one JSON object per line), machine + human readable
```json
{
"timestamp": "2026-06-27T14:22:33Z",
"request_id": "req-abc123def456",
"model_info": {
"name": "mistral:7b",
"version": "Q4_K_M",
"quantization": "Q4_K_M",

},
"inference": {
"input_tokens": 142,
"output_tokens": 87,

"filter_triggered": false,
"rejected_reason": null,
"confidence_score": 0.89
},
"system_state": {
"gpu_utilization_percent": 94,
"gpu_memory_mb": 8192,
"gpu_temp_celsius": 68,
"gpu_power_watts": 165,
"cpu_utilization_percent": 22,
"ambient_temp_celsius": 34
},
"data_provenance": {
"input_source": "user_query",

"eu_ai_act_category": "general_purpose_ai",
"nist_ai_impact_level": "moderate",
"data_lineage_preserved": true,
"audit_trail_intact": true
}
}
```
**Why these fields:**
- `inference_time_ms` + `gpu_power_watts` = efficiency data (for environmental regs)
- `safety_filtering` = demonstrates responsible deployment (AI Act Article 50)
- `data_provenance` = proves we're not using private/training data (AI Act transparency)
- `regulatory_context` = shows we understand classification framework
**Retention:** Keep daily logs for 5 years minimum. Archive older logs but never delete.
#### System Health Logging (`/srv/ai-logs/system-health/`)

### B. Documentation Standard (Built for Policy Input)
**Every major technical work produces TWO documents:**
#### 1. Technical Documentation
- **Audience:** Engineers, future maintainers, CE team
- **Content:** "Here's what we did and how it works"
- **Format:** Markdown, code examples, step-by-step
- **File:** `phase-N-technical.md`
#### 2. Regulatory Notes Document
- **Audience:** EU regulators, researchers, policy makers
- **Content:** "Here's what this means for policy and sovereignty"
- **Format:** Clear language, specific evidence, policy implications
- **File:** `phase-N-regulatory-notes.md`
**Example Structure (Phase 4: GPU Driver):**
**Technical:**
```markdown
# Phase 4: NVIDIA GPU Driver Installation
## Hardware
- GPU: ASUS Dual RTX 5060 Ti OC 16GB (Blackwell sm_120)
- Driver requirement: 555.42+
- Kernel: 6.12.0-211.7.3.el10_2 (AlmaLinux 10.2)
## Steps
1. Verify BIOS Secure Boot OFF
2. Install nvidia-driver-555
3. Verify with nvidia-smi
4. Test with ollama
```
**Regulatory Notes:**
```markdown
# Phase 4: GPU Deployment — Policy Implications
## Why Blackwell Hardware Matters for EU Sovereignty
- Blackwell (sm_120) is newest architecture as of June 2026
- Older GPUs (RTX 3090, RTX 4090) cannot run latest models efficiently
- Hardware refresh cycle: 3-4 years for SMEs running current AI
## Policy Finding: Hardware Cost is the Real Barrier
If EU mandates local AI for SME compliance:
- **Not software cost** (Ollama, AlmaLinux, Open WebUI all free/open)
- **Hardware amortization** is the blocker
- RTX 5060 Ti 16GB @ €280 is affordable; A100 @ €15K is not
## Recommendation to EU Policymakers
1. Consider device trade-in programs for AI hardware
2. Support refurbished GPU tier (RTX 4090, RTX 5090) for budget SMEs
3. Require drivers to remain available for 5+ years (currently NVIDIA: 3 years max)
## Evidence Generated
- Driver compatibility matrix: which GPUs work with which kernels
- Thermal efficiency data: Blackwell power consumption vs. RTX 3090
- Cost-to-TFLOPS ratio: quantified hardware budget reality for SMEs

## V. DECISION-MAKING FRAMEWORK (FOR CODE)
When working on any CE infrastructure or deployment decision, apply this framework:
### Question 1: Does this serve EU sovereignty?
- **Yes** → Consider it
- **No** → Reconsider or reject
- **Unknown** → Research, consult with John
### Question 2: Can we document and share this learning?
- **Yes** → Proceed; build logging/docs alongside code
- **No** → Simplify or redesign until shareable
- **Constraint** → If it can't be documented for regulators, question its necessity
### Question 3: Does this anticipate future regulation?
- **Yes** → Prioritize; log more than necessary
- **Somewhat** → Proceed with extra logging
- **No** → Still proceed, but don't add speculative logging
### Question 4: Will this become evidence?
- **Yes** → Make it reproducible, measurable, auditable
- **Maybe** → Log it anyway
- **No** → Still track it operationally, but lower priority on regulatory evidence
---
## VI. OPERATIONAL PRINCIPLES
### A. Logging is Not Optional
Every system (jahnet, BigBoy, Pi fleet, N100) produces structured logs at the rates shown above. This is as important as backups.
### B. Documentation Happens During Work, Not After
When coding Phase N:
- Write technical docs as you code (parallel, not sequential)
- Draft regulatory notes as you discover findings
- Don't wait for Phase 14 to decide what's policy-relevant
### C. Public Repos Are Contribution Channels, Not PR
Do not:
- Sanitize language to "look good"
- Omit negative findings ("this didn't work")
- Hide uncertainties
Do:
- Be honest about what succeeded and what failed
- Explain why choices were made
- Show the evidence clearly
- Recommend policy changes based on real constraints
### D. Contribution Doesn't Wait for Perfection
If Phase 11 reveals something unexpected (high thermal spike, filter false positives), document it immediately. Regulators learn from real problems, not polished case studies.
---
## VII. INTEGRATION WITH BIGBOY DEPLOYMENT
### Phase 0: Foundation
- ✓ Logging architecture (see Section III.A)
- ✓ Repository structure (see Section III.C)
- ✓ Documentation template (see Section III.B)
### Phases 1-13: Build with Contribution in Mind
- Each phase produces: technical.md + regulatory-notes.md
- Logs are structured per Section III.A standards
- Every decision is logged (not just errors)
### Phase 14: Observation + Submission
- Week 1-2: Collect metrics per Section III.A
- Week 3: Draft regulatory input per Section IV
- Week 4: Submit to targets per Section IV.B
### Post-Deployment: Sustained Contribution
- Monthly: Review logs for policy-relevant findings
- Quarterly: Publish updates to Codeberg
- As regulations evolve: Add new logging fields, document how we adapted
---
## VIII. WHAT CODE SHOULD KNOW
1. **You are not building a product. You are demonstrating a capability.**
- Every line of code is potential evidence for policy
- Logging is as important as functionality
2. **Simplicity is better than cleverness.**
- If a choice makes logs harder to understand, don't do it
- If it can't be documented for regulators, reconsider it
3. **Transparency is the default.**
- Assume everything (technical docs + logs) will be public
- No "internal notes" hidden from regulators
- Even failed experiments are valuable evidence
4. **John (the OHIOD) makes final calls.**
- Code surfaces options, evidence, recommendations
- John decides direction, guided by this policy
- Contribution framework is non-negotiable; implementation details are flexible
5. **This isn't extra work. It's the work.**
- Building without contribution is incomplete
- Logging is operational necessity, not compliance overhead
- Documentation is design input, not bureaucracy
---
## IX. SUCCESS METRICS (FOR THIS POLICY)
**Not measured by:**
- How fast deployment happens
- How many features are implemented
- How low costs are
**Measured by:**
- **Audit trail completeness** — Can a regulator trace every decision?
- **Documentation quality** — Can policy researchers understand our approach?
- **Contribution impact** — Did our evidence influence EU guidance?
- **Reproducibility** — Can another SME build the same system using our docs?
- **Honesty** — Did we document failures as clearly as successes?
---
## X. CODEBERG PUBLICATION STANDARDS
When pushing to `ceos/bigboy-regulatory-contribution`:
1. **No credentials, PIIs, or internal IPs**
- Generic hostnames: `hostname` not `bigboy`
- Generic IPs: `192.168.X.X` not `192.168.0.240`
- No API keys, SSH keys, or secrets
2. **All technical details public**
- Kernel versions, driver choices, hardware specs ✓
- Thermal baselines, power consumption, inference latency ✓
- Cost analysis, ROI calculations ✓
- "Secret sauce" that's proprietary? Don't include it (not relevant to policy anyway)
3. **Licensing: CC0 (Public Domain)**
- EU policymakers may use freely
- Other SMEs may fork and adapt
- No attribution required (though welcome)
4. **Invitation to Community**
```markdown
# Contributing Similar Case Studies
If you've deployed local AI in your region, please contribute:
- Your technical documentation
- Your regulatory notes
- Your evidence and metrics
This repository is for practitioners sharing real experience
with EU policymakers. The more voices, the better the policy.
```
---
## XI. CONTACT & ESCALATION
**For Code guidance on policy questions:**
- Unclear if something is contribution-worthy? Ask John
- Uncertain how to log something? Reference Section III.A or ask
- Not sure if a design choice serves sovereignty? Escalate to John
**For formal submission decisions:**
- John makes all final calls on what/when/how to submit to EU
- Code drafts recommendations; John decides
---
## XII. VERSION HISTORY
| Version | Date | Changes |
|---------|------|---------|
| 1.0 | 2026-06-27 | Initial handoff document, BigBoy-focused, ready for Phase 1 implementation |
---
## XIII. CLOSING STATEMENT
This policy exists because **CE believes EU AI-Cloud sovereignty is a public good, and practitioners have a responsibility to strengthen it.**
We are not trying to influence policy for profit. We are trying to influence policy because it matters, and we have evidence that regulators need to see.
Every line of code, every log entry, every documented decision is a contribution to something larger than BigBoy. It's a contribution to the European project of building technology that serves people, not platforms.
That's the commitment this handoff document represents.

# AI Services on AlmaLinux — Ollama, Open WebUI, Cockpit for BigBoy
**Reference for installing and configuring inference/management services on AlmaLinux 10.2**
---
## Service Architecture
| Service | Port | Purpose | Runs As |
|---------|------|---------|---------|
| **Ollama** | 11434 | Local inference engine (localhost only) | ollama (system user) |
| **Open WebUI** | 8080 | Web interface for Ollama (LAN-facing) | open-webui (system user) |
| **Cockpit** | 9090 | System management dashboard (LAN-facing) | cockpit (systemd managed) |
---
## Installation
### Ollama
**Install from official repository:**
```bash
curl -fsSL https://ollama.ai/install.sh | sh
```
This:
- Downloads and installs the ollama binary
- Creates `ollama` system user
- Installs systemd service unit
- Enables and starts the service
**Verify installation:**
```bash
ollama --version
systemctl status ollama
```
**Pull a model (after GPU driver is confirmed working):**
```bash
ollama pull mistral # Mistral Small 3.1 7B (smallest, fastest)
# Or for larger model:
ollama pull mistral:24b # 24B variant if VRAM available
```
---
### Open WebUI
**Install from package (if available in repos):**
```bash
sudo dnf install -y open-webui
```
**If not in repos, install via Python/pip (alternative):**
```bash
sudo dnf install -y python3 python3-pip
pip install --user open-webui
```
**Or: Run as a container (preferred for isolation):**
```bash
sudo dnf install -y podman
podman run -d --name open-webui \
-p 8080:8080 \
-v open-webui:/app/backend/data \
ghcr.io/open-webui/open-webui:latest
```
**Verify it's running:**
```bash
systemctl status open-webui
# Or if containerized:
podman ps | grep open-webui
```
**Test connection:**
```bash
curl http://localhost:8080
# Should return HTML (the Open WebUI frontend)
```
---
### Cockpit
**Install:**
```bash
sudo dnf install -y cockpit cockpit-podman cockpit-pcp
```
**Enable and start:**
```bash
sudo systemctl enable cockpit.socket
sudo systemctl start cockpit.socket
```
**Verify it's listening:**
```bash
sudo ss -tlnp | grep 9090
# Expected: tcp LISTEN ... :9090 ... cockpit
```
**Access via browser (from another machine on LAN):**
```
https://192.168.0.240:9090
# Login as john (with sudo privileges)
```
---
## Configuration
### Ollama — Environment Variables
**Location:** `/etc/default/ollama` (create if doesn't exist)
```bash
sudo cat > /etc/default/ollama <<'EOF'
# Ollama configuration for BigBoy
# GPU/CUDA settings
CUDA_VISIBLE_DEVICES=0 # Use GPU 0 (the RTX 5060 Ti)
OLLAMA_MAX_LOADED_MODELS=1 # Never load multiple models into VRAM simultaneously
OLLAMA_KEEP_ALIVE=5m # Unload model after 5 minutes of inactivity
# Memory management
OLLAMA_MAX_QUEUE=4 # Queue up to 4 requests, don't reject
OLLAMA_FLASH_ATTENTION=1 # Use flash attention (lower peak VRAM)
OLLAMA_GPU_OVERHEAD=536870912 # Reserve 512MB explicitly for GPU overhead
# Listening
OLLAMA_HOST=127.0.0.1:11434 # Localhost only (Open WebUI is the LAN interface)
# Logging (optional)
OLLAMA_DEBUG=0 # Set to 1 for verbose debug logs
EOF
```
**Reload after editing:**
```bash
sudo systemctl daemon-reload
sudo systemctl restart ollama
```
---
### Open WebUI — Configuration
**Connect to local Ollama:**
```
Open WebUI web interface → Settings → Backend
OLLAMA_API_BASE_URL: http://localhost:11434
```
**Optional: Persist configuration in environment:**
```bash
sudo cat >> /etc/default/open-webui <<'EOF'
OLLAMA_BASE_URL=http://127.0.0.1:11434
EOF
```
---
### Cockpit — HTTPS Certificate
**Cockpit requires HTTPS. Certificate is auto-generated on first start:**
```bash
ls -la /etc/cockpit/ws-certs.d/
# Should see auto-generated certificate
```
**On first connection, browser will warn about self-signed cert — accept it.**
**Optional: Use a real certificate (not needed for internal use):**
```bash
# Place your certificate and key in /etc/cockpit/ws-certs.d/
sudo cp your-cert.crt /etc/cockpit/ws-certs.d/
sudo cp your-key.key /etc/cockpit/ws-certs.d/
sudo systemctl restart cockpit
```
---
## Service Management
### Check status of all three:
```bash
systemctl status ollama
systemctl status open-webui # Or podman ps if containerized
systemctl status cockpit
```
### Start/stop/restart:
```bash
sudo systemctl start ollama
sudo systemctl stop ollama
sudo systemctl restart ollama
# Same for open-webui and cockpit
```
### Enable on boot:
```bash
sudo systemctl enable ollama
sudo systemctl enable open-webui
sudo systemctl enable cockpit
```
### View logs:
```bash
journalctl -u ollama -f # Follow Ollama logs
journalctl -u open-webui -f
journalctl -u cockpit -f
```
---
## Verification Checklist
**Run after all three services are installed and started:**
1. **Ollama is running and accessible:**
```bash
curl http://localhost:11434/api/version
# Expected: {"version": "x.x.x"}
```
2. **GPU is recognized by Ollama:**
```bash
ollama list
# Should show any pulled models
```
3. **Open WebUI can connect to Ollama:**
```bash
curl http://localhost:8080
# Should return HTML (not a connection error)
```
4. **Cockpit is listening on 9090:**
```bash
sudo ss -tlnp | grep 9090
```
5. **All ports are firewalled correctly** (see `alma-firewall.md`):
```bash
sudo firewall-cmd --list-ports
# Should show 8080/tcp, 9090/tcp (11434 NOT exposed to LAN)
```
---
## Troubleshooting
**Ollama won't start:**
- Check NVIDIA driver is loaded: `nvidia-smi`
- Check CUDA environment: `ollama --version` and `nvidia-smi`
- View error logs: `journalctl -u ollama -e`
**Open WebUI can't connect to Ollama:**
- Verify Ollama is listening: `curl http://localhost:11434/api/version`
- Check Open WebUI logs: `journalctl -u open-webui -e`
- Verify firewall isn't blocking localhost (it shouldn't): `sudo firewall-cmd --list-all`
**Cockpit won't open in browser:**
- Verify it's listening: `sudo ss -tlnp | grep 9090`
- Try `https://` not `http://` (HTTPS required)
- Check firewall allows 9090 from your client IP
**GPU memory exhaustion:**
- Set `OLLAMA_MAX_LOADED_MODELS=1` to avoid multiple models in VRAM
- Reduce `OLLAMA_KEEP_ALIVE` to unload faster
- Monitor GPU memory: `nvidia-smi` or `watch -n 1 nvidia-smi`
---
## Next Steps
1. Verify all three services are running (see Verification Checklist)
2. Configure firewall rules (see `alma-firewall.md`)
3. Test inference: `ollama pull mistral && ollama run mistral "Hello"`
4. Access Open WebUI from another machine: `http://192.168.0.240:8080`
5. Log into Cockpit: `https://192.168.0.240:9090`

# Firewall Configuration on AlmaLinux — BigBoy Network Security
**Reference for firewalld configuration on AlmaLinux 10.2 for BigBoy's LAN services**
---
## firewalld Basics
**AlmaLinux uses firewalld by default** (not iptables directly). It's zone-based, runtime + persistent rules.
### Key Concepts
- **Zones**: Predefined security levels (public, trusted, home, internal, etc.)
- **Runtime rules**: Effective immediately, lost on reboot
- **Permanent rules**: Survive reboot, added with `--permanent` flag
- **Services**: Pre-configured rules bundled by service name (ssh, http, https, etc.)
- **Ports**: Open specific TCP/UDP ports
---
## BigBoy Firewall Requirements
| Port | Protocol | Service | Direction | Purpose |
|------|----------|---------|-----------|---------|
| 22 | TCP | SSH | Inbound | Remote administration |
| 8080 | TCP | Open WebUI | Inbound (LAN only) | Web interface for Ollama |
| 9090 | TCP | Cockpit | Inbound (LAN only) | System management |
| 11434 | TCP | Ollama | Local only | Should NOT be LAN-facing |
---
## Initial Setup
**Check firewall status:**
```bash
sudo systemctl status firewalld
sudo firewall-cmd --state
# Expected: running, connected
```
**Enable on boot:**
```bash
sudo systemctl enable firewalld
```
**View current zone:**
```bash
sudo firewall-cmd --get-default-zone
# Usually: public (for dynamic networks)
# Change to 'home' or 'internal' if you prefer (more permissive)
```
---
## Configuration for BigBoy
### Option 1: Keep "public" zone (recommended for security)
**Add SSH (required for management):**
```bash
sudo firewall-cmd --add-service=ssh --permanent
```
**Add HTTP and HTTPS (for web services):**
```bash
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --add-service=https --permanent
```
**Or add specific ports directly:**
```bash
sudo firewall-cmd --add-port=8080/tcp --permanent # Open WebUI
sudo firewall-cmd --add-port=9090/tcp --permanent # Cockpit
# Don't open 11434 — Ollama stays localhost-only
```
**Reload rules:**
```bash
sudo firewall-cmd --reload
```
**Verify:**
```bash
sudo firewall-cmd --list-ports
# Expected: 8080/tcp 9090/tcp
sudo firewall-cmd --list-services
# Expected: ssh (and http/https if you added them)
```
---
### Option 2: Restrict to specific LAN subnet (more secure)
**If you want to restrict access to just your home LAN (e.g., 192.168.0.0/24):**
```bash
# Change zone to 'internal' or create a custom zone
sudo firewall-cmd --set-default-zone=internal
# Add services to the zone
sudo firewall-cmd --zone=internal --add-service=ssh --permanent
sudo firewall-cmd --zone=internal --add-port=8080/tcp --permanent
sudo firewall-cmd --zone=internal --add-port=9090/tcp --permanent
# Restrict the zone to your LAN
sudo firewall-cmd --zone=internal --add-source=192.168.0.0/24 --permanent
# Set public zone to drop everything else (strict)
sudo firewall-cmd --set-default-zone=public
sudo firewall-cmd --zone=public --set-target=DROP --permanent
# Reload
sudo firewall-cmd --reload
```
**Verify (this configuration):**
```bash
sudo firewall-cmd --zone=internal --list-ports
sudo firewall-cmd --zone=internal --list-sources
sudo firewall-cmd --zone=public --get-target
```
---
## Runtime vs. Permanent Rules
**Add a rule for the current session only (lost on reboot):**
```bash
sudo firewall-cmd --add-port=8080/tcp
# No --permanent flag
```
**Make it permanent (survives reboot):**
```bash
sudo firewall-cmd --add-port=8080/tcp --permanent
sudo firewall-cmd --reload
```
**If you add runtime rules, always persist them before reboot:**
```bash
sudo firewall-cmd --runtime-to-permanent
sudo firewall-cmd --reload
```
---
## Port Blocking — Ensure Ollama Stays Private
**Verify 11434 is NOT open to the network:**
```bash
sudo firewall-cmd --list-ports
# 11434 should NOT appear in this list
# Also verify nothing is listening on 0.0.0.0:11434
sudo ss -tlnp | grep 11434
# Expected: tcp 127.0.0.1:11434 (NOT 0.0.0.0:11434)
```
**If 11434 accidentally got exposed, remove it:**
```bash
sudo firewall-cmd --remove-port=11434/tcp --permanent
sudo firewall-cmd --reload
```
---
## Common Operations
**Add a service (pre-defined rules):**
```bash
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --reload
```
**Remove a service:**
```bash
sudo firewall-cmd --remove-service=http --permanent
sudo firewall-cmd --reload
```
**List available services:**
```bash
sudo firewall-cmd --get-services | tr ' ' '\n'
# Shows all built-in service definitions (ssh, http, https, etc.)
```
**Add a custom service (advanced):**
```bash
# Create a custom service file
sudo cat > /etc/firewalld/services/ollama-local.xml <<'EOF'
<?xml version="1.0" encoding="utf-8"?>
<service>
<short>Ollama Local</short>
<description>Ollama inference (localhost only)</description>
<port protocol="tcp" port="11434"/>
</service>
EOF
# Reload firewall to recognize it
sudo firewall-cmd --reload
```
---
## Debugging Connectivity Issues
**Connection refused to port 8080?**
1. Verify the service is actually listening:
```bash
sudo ss -tlnp | grep 8080
# Should show: tcp ... LISTEN ... open-webui or container process
```
2. Verify firewall allows it:
```bash
sudo firewall-cmd --list-ports
sudo firewall-cmd --list-services
```
3. Check if it's a zone issue:
```bash
sudo firewall-cmd --get-active-zones
sudo firewall-cmd --zone=public --list-ports
```
**Connection times out from a specific IP?**
- Check if IP is in the allowed source range:
```bash
sudo firewall-cmd --zone=internal --list-sources
```
- Or if using public zone only, allow the IP:
```bash
sudo firewall-cmd --add-source=192.168.0.10 --zone=internal --permanent
sudo firewall-cmd --reload
```
**Want to temporarily allow all traffic for testing?**
```bash
# WARNING: This opens everything — use only for debugging
sudo firewall-cmd --set-default-zone=trusted
sudo firewall-cmd --reload
# After testing, revert:
sudo firewall-cmd --set-default-zone=public
sudo firewall-cmd --reload
```
---
## BigBoy Recommended Configuration (Summary)
```bash
# 1. Ensure firewalld is enabled
sudo systemctl enable firewalld
sudo systemctl start firewalld
# 2. Add essential services
sudo firewall-cmd --add-service=ssh --permanent
# 3. Open ports for web services (LAN-accessible)
sudo firewall-cmd --add-port=8080/tcp --permanent # Open WebUI
sudo firewall-cmd --add-port=9090/tcp --permanent # Cockpit
# 4. Ensure Ollama port is NOT exposed
# (verify 11434 is not in the list above)
# 5. Reload and verify
sudo firewall-cmd --reload
sudo firewall-cmd --list-ports
sudo firewall-cmd --list-services
```
---
## Monitoring & Logs
**View firewall events (helpful for debugging):**
```bash
sudo journalctl -u firewalld -f
```
**Monitor active connections:**
```bash
sudo ss -tlnp
# Shows all listening ports and their owning processes
```
**Test connectivity from another machine on LAN:**
```bash
# From another computer, test if you can reach BigBoy:
curl http://192.168.0.240:8080 # Open WebUI
curl -k https://192.168.0.240:9090 # Cockpit (HTTPS, ignore cert warning)
ssh john@192.168.0.240 # SSH
```
---
## Advanced: NAT and Port Forwarding
**If you want to expose services to the internet (not recommended without more security):**
```bash
# Forward external port 8080 to internal 8080
sudo firewall-cmd --add-forward-port=port=8080:proto=tcp:toport=8080 --permanent
sudo firewall-cmd --reload
```
**Do not do this for production without proper VPN/TLS/authentication setup.**
---
## Reference: firewalld vs. iptables
**firewalld** (what we use on AlmaLinux):
- Manages zones and services
- Easier to understand and configure
- Runtime changes + permanent rules
- Recommended for modern RHEL/Alma
**iptables** (older, lower-level):
- Direct packet filtering rules
- More powerful but steeper learning curve
- Firewalld is actually built on iptables under the hood
**For BigBoy, stick with firewalld.** It's simpler and sufficient.

# NVIDIA Driver Installation on AlmaLinux 10.2 (RHEL-compatible)
**Reference for installing official NVIDIA driver on BigBoy — RTX 5060 Ti (Blackwell, sm_120)**
---
## Pre-Installation Checklist
**Verify GPU is detected:**
```bash
lspci | grep -i nvidia
# Expected output: [10de:2d04] — RTX 5060 Ti
```
**Disable nouveau (open-source driver):**
```bash
echo "blacklist nouveau" | sudo tee -a /etc/modprobe.d/blacklist-nouveau.conf
echo "options nouveau modeset=0" | sudo tee -a /etc/modprobe.d/blacklist-nouveau.conf
sudo dracut --force # Rebuild initramfs with blacklist applied
sudo reboot # Required to unload nouveau
```
**Verify nouveau is not loaded after reboot:**
```bash
lsmod | grep nouveau # Should be empty
```
---
## Install Build Dependencies
**Required for compiling the driver:**
```bash
sudo dnf groupinstall -y "Development Tools"
sudo dnf install -y kernel-headers kernel-devel gcc make
```
Verify kernel-devel matches running kernel:
```bash
uname -r # Running kernel version
rpm -q kernel-devel # Installed kernel-devel version
# Should match exactly
```
---
## Download Official NVIDIA Driver
**For RTX 5060 Ti on RHEL/AlmaLinux 10 (x86_64):**
1. Visit https://www.nvidia.com/Download/driverDetails.aspx (or search "NVIDIA driver download RTX 5060 Ti")
2. Select:
- Product Type: **GeForce**
- Product Series: **GeForce RTX 50 Series**
- Product: **RTX 5060 Ti**
- OS: **Linux 64-bit**
- Download the `.run` installer
Alternatively, download via command line (adjust version as needed):
```bash
cd ~/Downloads
wget https://us.download.nvidia.com/XFree86/Linux-x86_64/[VERSION]/NVIDIA-Linux-x86_64-[VERSION].run
chmod +x NVIDIA-Linux-x86_64-[VERSION].run
```
---
## Installation Steps
**1. Exit graphical environment (if running):**
```bash
sudo systemctl isolate multi-user.target # Drop to text-only console
# Or: Ctrl+Alt+F3 to switch to text console
```
**2. Run the installer:**
```bash
cd ~/Downloads
sudo ./NVIDIA-Linux-x86_64-[VERSION].run
```
**3. Installer prompts — typical responses:**
- "Accept EULA?" → **Yes**
- "Install 32-bit support?" → **No** (not needed for BigBoy)
- "Install NVIDIA's OpenGL libraries?" → **Yes**
- "Update X configuration file?" → **No** (BigBoy is headless; no X11)
- "Install NVIDIA application profiles?" → **Yes**
**4. Verify installation:**
```bash
nvidia-smi # Should show GPU info, memory, driver version
```
**Expected output (example):**
```
Fri Jun 27 14:30:45 2026
+--------------------------------------------+-----------+
| NVIDIA-SMI 595.84 Driver Version: 595.84 |
|----------------------------------------------+------------|
| GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr. ECC |
| No Running Processes |
+--------------------------------------------+-----------+
```
---
## Post-Installation
**Load NVIDIA kernel module:**
```bash
sudo modprobe nvidia
sudo modprobe nvidia-uvm
lsmod | grep nvidia # Should show nvidia, nvidia_uvm, nvidia_drm
```
**Verify CUDA support:**
```bash
nvidia-smi -q | grep "Compute Capability"
# Expected for RTX 5060 Ti: 10.0 (Compute Capability for Blackwell)
```
---
## Persistent Module Loading
**Ensure nvidia modules load at boot:**
```bash
echo "nvidia" | sudo tee -a /etc/modules-load.d/nvidia.conf
echo "nvidia-uvm" | sudo tee -a /etc/modules-load.d/nvidia.conf
```
**Verify on next reboot:**
```bash
sudo reboot
# After reboot:
lsmod | grep nvidia
nvidia-smi
```
---
## Troubleshooting
**nvidia-smi command not found:**
- Ensure installer completed without errors.
- Check PATH includes `/usr/bin`:
```bash
which nvidia-smi
/usr/bin/nvidia-smi # Should be in /usr/bin
```
**"Failed to initialize NVML: Driver/library version mismatch":**
- A mismatch between loaded driver and user-space tools.
- Reboot to ensure clean driver reload: `sudo reboot`
**nouveau still showing in lsmod after reboot:**
- Dracut rebuild may not have worked. Try:
```bash
sudo dnf remove -y xorg-x11-drm* # Remove X11 DRM drivers that might pull nouveau
sudo dracut --force
sudo reboot
```
**Kernel module compilation failed:**
- Check for errors in installer output.
- Verify kernel-devel version matches running kernel: `uname -r` vs `rpm -q kernel-devel`
- If versions don't match, install matching kernel-devel or update kernel:
```bash
sudo dnf install kernel-devel-$(uname -r) # Install exact match
```
---
## For BigBoy Specifically
**Full sequence (assuming clean AlmaLinux 10.2 install):**
```bash
# 1. Disable nouveau and reboot (see above)
echo "blacklist nouveau" | sudo tee -a /etc/modprobe.d/blacklist-nouveau.conf
echo "options nouveau modeset=0" | sudo tee -a /etc/modprobe.d/blacklist-nouveau.conf
sudo dracut --force
sudo reboot
# 2. Install build dependencies (after reboot)
sudo dnf groupinstall -y "Development Tools"
sudo dnf install -y kernel-headers kernel-devel gcc make
# 3. Download and run installer
cd ~/Downloads
wget https://us.download.nvidia.com/XFree86/Linux-x86_64/595.84/NVIDIA-Linux-x86_64-595.84.run
chmod +x NVIDIA-Linux-x86_64-595.84.run
sudo ./NVIDIA-Linux-x86_64-595.84.run
# 4. Load modules and verify
sudo modprobe nvidia nvidia-uvm
nvidia-smi
# 5. Make persistent
echo "nvidia" | sudo tee -a /etc/modules-load.d/nvidia.conf
echo "nvidia-uvm" | sudo tee -a /etc/modules-load.d/nvidia.conf
```
---
## Update Path (future reference)
When NVIDIA releases a new driver:
1. Download new `.run` installer
2. Repeat installation steps (kernel-devel should auto-match via dnf)
3. Reboot
4. Verify with `nvidia-smi`
For production systems, consider NVIDIA's DKMS package (`nvidia-dkms`) which auto-rebuilds the kernel module on kernel updates — see NVIDIA's RHEL/Alma documentation for DKMS setup.

# AlmaLinux Package Management for BigBoy
**Reference for dnf/rpm operations on AlmaLinux 10.2 (RHEL-compatible)**
---
## dnf Basics
**Update package lists and system:**
```bash
sudo dnf update # Update all installed packages
sudo dnf upgrade # Same as update (dnf alias)
sudo dnf check-update # Check for available updates without installing
```
**Search and install:**
```bash
sudo dnf search <package> # Search for a package
sudo dnf info <package> # Show package details
sudo dnf install <package> # Install a package
sudo dnf install -y <package> # Install without confirmation prompt
```
**Remove packages:**
```bash
sudo dnf remove <package> # Remove a package
sudo dnf autoremove # Remove unused dependencies
```
**List installed packages:**
```bash
dnf list installed # All installed packages
dnf list installed | grep <name> # Search installed packages
```
**Repository management:**
```bash
sudo dnf config-manager --enable <repo> # Enable a repository
sudo dnf config-manager --disable <repo> # Disable a repository
dnf repolist # List all enabled repos
```
---
## Common Packages for BigBoy
**Build essentials (for compiling NVIDIA driver):**
```bash
sudo dnf groupinstall "Development Tools"
sudo dnf install kernel-headers kernel-devel gcc make
```
**Utilities:**
```bash
sudo dnf install vim git htop tmux curl wget
sudo dnf install btrfs-progs smartmontools
```
**Network/firewall:**
```bash
sudo dnf install firewalld # Firewall daemon
sudo dnf install bind-utils # dig, nslookup for DNS testing
```
---
## rpm Direct Operations
**Query installed packages:**
```bash
rpm -qa | grep <package> # List all matching installed packages
rpm -qi <package> # Show detailed info on an installed package
rpm -ql <package> # List files in an installed package
```
**Install from .rpm file:**
```bash
sudo dnf install ./package-file.rpm # Install local .rpm using dnf
sudo rpm -ivh ./package-file.rpm # Install using rpm directly (older method)
```
---
## Key Differences from Debian
| Task | Debian/Ubuntu | AlmaLinux/RHEL |
|------|---|---|
| Update system | `apt update && apt upgrade` | `dnf update` |
| Install package | `apt install <pkg>` | `dnf install <pkg>` |
| Search package | `apt-cache search <pkg>` | `dnf search <pkg>` |
| Remove package | `apt remove <pkg>` | `dnf remove <pkg>` |
| Build tools | `build-essential` | `Development Tools` group |
| Kernel headers | `linux-headers-generic` | `kernel-headers` + `kernel-devel` |
| Clean cache | `apt clean` | `dnf clean all` |
---
## Troubleshooting
**dnf is slow:**
- First run may cache metadata. Subsequent runs are faster.
- Check `/var/cache/dnf/` for stale cache: `sudo dnf clean all` then retry.
**Broken dependencies:**
```bash
sudo dnf check # Check for dependency issues
sudo dnf distro-sync # Resolve dependency conflicts
```
**Downgrade a package:**
```bash
sudo dnf downgrade <package>
```
---
## For BigBoy Specifically
**One-time setup after fresh AlmaLinux install:**
```bash
sudo dnf update -y # Update all packages
sudo dnf groupinstall -y "Development Tools" # Build essentials
sudo dnf install -y kernel-headers kernel-devel # Kernel dev for NVIDIA driver
sudo dnf install -y vim git htop curl wget # Utilities
sudo dnf install -y firewalld # Firewall
```
Then proceed to NVIDIA driver installation (see `alma-nvidia-driver.md`).

# Phase 1: Base OS Installation & Foundation Workflow
**BigBoy AlmaLinux 10.2 Unattended Installation via Anaconda Kickstart**
**Duration:** ~1.5-2 hours (mostly automated)
**Scope:** OS installation, first boot, SSH setup, logging directory staging
**Output:** BigBoy ready for Phase 2 system configuration
---
## Pre-Flight Checklist
Before beginning Phase 1 installation:
### Hardware Verification
- [ ] BigBoy hardware fully assembled
- [ ] RTX 5060 Ti GPU seated (PCIe slot powered on in BIOS)
- [ ] All 5 drives connected (1× NVMe, 4× SATA)
- [ ] Network cable connected to `enp4s0` (192.168.0.0/24 LAN)
- [ ] Console access available (monitor/keyboard, or serial/IPMI)
- [ ] Power supply connected and tested
### Network Readiness
- [ ] DHCP server running on bench LAN (should assign 192.168.0.x)
- [ ] Network accessible from BigBoy (ping 8.8.8.8 from BIOS/UEFI boot menu if possible)
- [ ] Firewall allows BigBoy DHCP on bench LAN
- [ ] SSH access from Workbench to 192.168.0.240 will work (once IP assigned)
### Media & Kickstart Preparation
- [ ] AlmaLinux 10.2 minimal ISO downloaded (bootable USB prepared)
- [ ] Kickstart file copied to USB or accessible via HTTP: `/home/john/projects/bigboy-setup/alma10-minimal-bigboy.ks`
- [ ] Method chosen: USB with local kickstart OR HTTP kickstart from Workbench
### Workbench Readiness
- [ ] SSH key generated: `~/.ssh/id_ed25519` (or existing key ready)
- [ ] Terminal open, ready to SSH to BigBoy post-install
- [ ] Ansible workspace ready: `/home/john/projects/bigboy-setup/`
---
## Kickstart Overview (What Happens Automatically)
The kickstart file (`alma10-minimal-bigboy.ks`) automates:
### OS Installation (Anaconda)
```
✓ AlmaLinux 10.2 minimal (text mode)
✓ Network: DHCP on enp4s0 (hostname: bigboy)
✓ Language: en_US.UTF-8
✓ Timezone: Europe/Rome UTC
✓ Root password: locked (no password login)
✓ Services: sshd enabled, NetworkManager enabled
```
### Partitioning & Filesystem
```
NVMe (/dev/nvme0n1):
└── Partition 1 (EFI): 1 GB, vfat, mounted at /boot/efi
└── Partition 2 (OS): ~499 GB, btrfs, mounted at /
SATA Drives (4× /dev/sd{a,b,c,d}):
└── /dev/sda (RAG Library): single btrfs partition (mounted in Phase 3)
└── /dev/sdb (Prompt Library): single btrfs partition (mounted in Phase 3)
└── /dev/sdc (Backup): single btrfs partition (mounted in Phase 3)
└── /dev/sdd (AI Logs): single btrfs partition (mounted in Phase 3)
```
**Note:** SATA drives created but NOT mounted during kickstart. Phase 3 (Ansible) handles subvolume creation and mounting.
### Bootloader
```
✓ systemd-boot (UEFI, modern standard)
✓ Boot drive: NVMe
✓ EFI variables configured
```
### Packages (Minimal Set)
```
Core:
- @core group (base OS packages)
- kernel + kernel-devel + kernel-headers (needed for NVIDIA driver compilation in Phase 4)
- grub2, shim, efibootmgr
Build essentials (for Phase 4 GPU driver):
- gcc, make, patch, perl
Utilities:
- curl, wget, vim, git, tmux, htop
- openssh-client, openssh-server, sudo
- btrfs-progs (for filesystem management)
- smartmontools (for SMART health checks)
Repositories:
- BaseOS (core)
- AppStream (applications)
- CRB (build tools)
- EPEL (extra packages)
```
### Post-Installation (Automatic)
```
✓ SSH daemon enabled and started
✓ /srv/deployment-log created (Ansible will log here)
✓ Nouveau driver blacklisted (step toward Phase 4 GPU driver)
✓ Initramfs rebuilt without nouveau
✓ Kickstart log written to /srv/deployment-log/kickstart.log
✓ System reboots automatically
```
---
## Installation Methods
### Method A: USB Kickstart (Recommended for First Boot)
**Preparation on Workbench:**
```bash
# 1. Download AlmaLinux 10.2 minimal ISO
mkdir -p ~/Downloads/alma
cd ~/Downloads/alma
wget https://repo.almalinux.org/almalinux/10/isos/x86_64/AlmaLinux-10-latest-x86_64-minimal.iso
# 2. Verify ISO (optional but recommended)
wget https://repo.almalinux.org/almalinux/10/isos/x86_64/CHECKSUM
sha256sum -c CHECKSUM | grep AlmaLinux-10.*minimal
# 3. Create bootable USB (replace /dev/sdX with actual USB device)
sudo dd if=AlmaLinux-10-latest-x86_64-minimal.iso of=/dev/sdX bs=4M status=progress
sudo sync
# 4. Mount USB and add kickstart file
# The dd command writes the ISO to the USB, creating a bootable filesystem on partition 1
# Mount that partition to add the kickstart file
# Identify your USB device (replace sdX with actual device, e.g., sdc)
lsblk # or: sudo fdisk -l
# Look for your USB device (e.g., /dev/sdc, 8GB size)
# Create mount point
mkdir -p /mnt/usb
# Mount the USB filesystem (note: partition 1, not the device itself)
sudo mount /dev/sdX1 /mnt/usb
# Verify the mount worked (should see AlmaLinux ISO contents)
ls /mnt/usb
# Expected output: EFI/, Packages/, images/, isolinux/, ks.cfg, etc.
# Copy kickstart file to USB root as ks.cfg
sudo cp /home/john/projects/bigboy-alma/alma10-minimal-bigboy.ks /mnt/usb/ks.cfg
# Verify the kickstart file is present
ls -la /mnt/usb/ks.cfg
# Unmount the USB
sudo umount /mnt/usb
# Eject the USB (optional but clean)
sudo eject /dev/sdX
```
**At BigBoy Console:**
```
1. Insert USB, power on BigBoy
2. Enter BIOS/UEFI boot menu (DEL, F2, or ESC during POST)
3. Select USB as boot device
4. Anaconda installer loads
5. At boot prompt, type:
inst.ks=file:///ks.cfg
(References ks.cfg on the USB root)
6. Press Enter → Unattended installation begins
```
### Method B: HTTP Kickstart (Alternative)
**Preparation on Workbench:**
```bash
# 1. Start simple HTTP server in bigboy-setup directory
cd /home/john/projects/bigboy-setup
python3 -m http.server 8000 &
# 2. Verify accessible
curl http://192.168.0.100:8000/alma10-minimal-bigboy.ks | head
```
**At BigBoy Console:**
```
1. Insert USB, power on BigBoy
2. Enter BIOS/UEFI boot menu
3. Select USB as boot device
4. At boot prompt, type:
inst.ks=http://192.168.0.100:8000/alma10-minimal-bigboy.ks
5. Press Enter → Unattended installation begins
```
**Advantage:** No need to prepare USB with ks.cfg file separately.
**Disadvantage:** Workbench must be reachable from BigBoy during install.

- Post-script execution: 1-2 min
- Reboot: 1-2 min
- First boot to SSH ready: 2-3 min
- **Total: ~20-25 minutes of actual installation**
### Network During Installation
Anaconda will:
1. Detect NIC (enp4s0)
2. Request DHCP address
3. Likely receive: 192.168.0.240 (or nearby IP)
4. Use DHCP IP to download packages from AlmaLinux mirrors
5. Store IP in DHCP lease (not persistent; check after reboot)
---
## First Boot & Network Configuration
### Verify BigBoy is Up
**From Workbench:**
```bash
# 1. Ping BigBoy (check if it got an IP)
ping 192.168.0.240
# Or try to discover:
nmap -sn 192.168.0.0/24 | grep -A1 "MAC Address"
# 2. Once IP known, SSH to root
ssh -i ~/.ssh/id_ed25519 root@192.168.0.240
# If SSH asks for password (kickstart didn't set one):
# → Accept this is expected; we'll add SSH keys in Phase 2
# → Login with empty password (root --locked in kickstart prevents normal login)
# → Or use console access
# Verify first boot
root@bigboy:~# uname -a
Linux bigboy 6.12.0-... #1 SMP ... x86_64 GNU/Linux
root@bigboy:~# lsb_release -a
AlmaLinux 10 ...
root@bigboy:~# hostnamectl
Static hostname: bigboy
root@bigboy:~# timedatectl
Time zone: Europe/Rome (CEST, +0200)
```
### Check Network Configuration
```bash
root@bigboy:~# ip addr show enp4s0
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP
inet 192.168.0.240/24 bcast 192.168.0.255 scope global dynamic enp4s0
root@bigboy:~# ip route show
default via 192.168.0.1 dev enp4s0 proto dhcp metric 100
root@bigboy:~# cat /etc/hostname
bigboy
root@bigboy:~# nmcli con show
NAME UUID TYPE DEVICE
System eth0 ... 802-3 enp4s0 (DHCP active)
```
**Observation:**
- IP is DHCP-assigned (will change on reboot if no DHCP reservation)
- Hostname is `bigboy` ✓
- Timezone is Europe/Rome ✓
- SSH is running ✓
### Verify Disks & Partitions
```bash
root@bigboy:~# lsblk
NAME SIZE TYPE FSTYPE MOUNTPOINTS
nvme0n1 500G disk
├─nvme0n1p1 1G part vfat /boot/efi
└─nvme0n1p2 499G part btrfs /
sda 2.0T disk (no mount, Phase 3)
sdb 2.0T disk (no mount, Phase 3)
sdc 2.0T disk (no mount, Phase 3)
sdd 2.0T disk (no mount, Phase 3)
root@bigboy:~# df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/nvme0n1p2 499G 2.0G 497G 1% /
root@bigboy:~# btrfs filesystem show /
Label: none uuid: 5daac1d7-10b3-498a-82b0-a4498d7e0717
Total devices 1 FS bytes 2.00GiB
devid 1 size 499GiB used 2.00GiB path /dev/nvme0n1p2
```
**Observations:**
- ✓ NVMe has 2 partitions (EFI + OS)
- ✓ OS partition is btrfs, mounted at `/`
- ✓ 4× SATA drives visible but unmounted (expected for Phase 3)
- ✓ NVMe UUID matches `5daac1d7-10b3-498a-82b0-a4498d7e0717` from HARDWARE.md ✓
---
## SSH Key Setup (Foundation for Phase 2+)
### Generate SSH Key (First Time Only)
**On Workbench (if not already done):**
```bash
# Generate Ed25519 key (if missing)
ssh-keygen -t ed25519 -a 100 -f ~/.ssh/id_ed25519 -N ""
# Verify key exists
ls -la ~/.ssh/id_ed25519*
```
### Deploy SSH Key to BigBoy
**From Workbench:**
```bash
# Copy public key to BigBoy
ssh-copy-id -i ~/.ssh/id_ed25519.pub root@192.168.0.240
# This will prompt for password
# Kickstart has "rootpw --locked", but you may be able to login with empty password
# If prompted, press Enter (empty password)
# Or manual method (if ssh-copy-id doesn't work):
cat ~/.ssh/id_ed25519.pub | ssh -i ~/.ssh/id_ed25519 root@192.168.0.240 \
"mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"
```
### Test Key-Based Login
```bash
# From Workbench, test passwordless SSH
ssh -i ~/.ssh/id_ed25519 root@192.168.0.240 "echo 'SSH key auth works'"
# Expected output:
# SSH key auth works
```
**If this succeeds:** SSH key-based auth is ready for Ansible in Phase 2.
---
## Logging Directory Verification
### Check Deployment Log Structure
**On BigBoy:**
```bash
root@bigboy:~# ls -la /srv/deployment-log/
total 12
-rw-r--r-- 1 root root 234 Jun 27 14:23 kickstart.log
root@bigboy:~# cat /srv/deployment-log/kickstart.log
Kickstart installation completed at Thu Jun 27 14:23:45 UTC 2026
Hostname: bigboy
Kernel: 6.12.0-211.7.3.el10_1.x86_64
# Check permissions (must be writable for Ansible)
root@bigboy:~# ls -ld /srv/deployment-log/
drwxr-xr-x 2 root root 4096 Jun 27 14:23 /srv/deployment-log/
```
**Expected:**
- ✓ Directory exists and is writable by root
- ✓ Kickstart log present with completion timestamp
- ✓ Ready for Ansible to write Phase 2+ logs
---
## System Readiness Checklist

---
## Automated Health Check Script
**Optional: Run this after first boot to verify Phase 1 completeness**
**On BigBoy (save as `/root/phase1-check.sh`):**
```bash
#!/bin/bash
set -e
echo "=== Phase 1 Readiness Check ==="
echo ""
echo "OS:"
lsb_release -a | head -1
uname -r
echo ""
echo "Network:"
ip addr show enp4s0 | grep "inet " | awk '{print $2}'
echo ""
echo "Disks:"
lsblk | grep -E "^nvme|^sda|^sdb|^sdc|^sdd"
echo ""
echo "Filesystems:"
btrfs filesystem show / | head -1
echo ""
echo "SSH:"
systemctl status sshd | grep "Active:"
echo ""
echo "Deployment Log:"
ls -la /srv/deployment-log/
echo ""
echo "=== Phase 1 Complete ==="
```
**Run:**
```bash
root@bigboy:~# bash /root/phase1-check.sh
```
---
## Progression to Phase 2
Once Phase 1 verification complete:
1. **Document IP address**
- Note actual DHCP IP (or set static if preferred)
- Update Ansible inventory if needed: `/projects/bigboy-setup/ansible/inventory.ini`
2. **Backup system state**
- Optional: Take snapshot of NVMe before Phase 2
```bash
btrfs subvolume snapshot -r / /phase-1-snapshot
```
3. **Proceed to Phase 2**
- Move to `/projects/bigboy-alma/alma-phase2-system-config-workflow.md`
- Phase 2 will configure system, finalize disk layout, prepare for Phase 3
---
## Troubleshooting Phase 1
### Kickstart File Not Found
```
Error: Unable to find kickstart file
```
**Solution:**
- Verify kickstart filename: should be `ks.cfg` (or exact path in `inst.ks=...`)
- Check USB mount: `sudo mount /dev/sdX1 /mnt && ls /mnt/ks.cfg`
- Try HTTP method instead
### Network Not Connecting
```
Installation hanging at "Configuring network"
```
**Solution:**
- Verify DHCP server running on bench LAN
- Check cable connection
- Enable BIOS Wake-on-LAN if available
- Try manual network config: press `<Tab>` at boot, edit `inst.ks=...` to add IP
### Anaconda Crashes or Hangs
```
Text mode installer freezes
```
**Solution:**
- Try BIOS setting: disable UEFI, use Legacy BIOS
- Reduce package list in kickstart (remove optional packages)
- Check for USB corruption: recreate USB boot media
### SSH Not Accessible After Install
```
ssh: connect to host 192.168.0.240 port 22: Connection refused
```
**Solution:**
- Verify SSH is running: `systemctl status sshd` on BigBoy console
- Check firewall: `firewall-cmd --list-all` (firewall may block by default)
- Check IP address: `ip addr show enp4s0`
### No Internet During Installation
```
Package installation fails; mirrors unreachable
```
**Solution:**
- Verify bench LAN has internet access
- Check default gateway: `ip route show`
- Try alternative mirror in kickstart: edit `url --url=...` line
- Use local package repository if available
---

# ============================================================================
# DISK PARTITIONING SCHEME
# ============================================================================
#
# Design:
# NVMe (500GB): EFI boot (1GB) + btrfs OS (~499GB)
# SATA Drive 1 (RAG): Single btrfs partition (mounted by Phase 3 Ansible)
# SATA Drive 2 (Prompt): Single btrfs partition (mounted by Phase 3 Ansible)
# SATA Drive 3 (Backup): Single btrfs partition (mounted by Phase 3 Ansible)
# SATA Drive 4 (AI Logs): Single btrfs partition (mounted by Phase 3 Ansible)
#
# Important: SATA partitions are created but NOT mounted during kickstart.
# Phase 3 Ansible role handles subvolume creation, mounting, and fstab.
# ============================================================================
# Do not erase existing partitions (safety measure)
clearpart --none --initlabel
# ============================================================================
# NVMe PARTITIONING (Primary OS drive)
# ============================================================================
# Partition 1: EFI System Partition
# Size: 1 GB (sufficient for kernel + bootloader)
# Filesystem: vfat (EFI standard)
# Mount: /boot/efi (handled by Anaconda)
part /boot/efi --fstype=efi --size=1024 --ondrive=nvme0n1
# Partition 2: OS Root (btrfs)
# Size: Grow to fill remaining NVMe space (~499 GB)
# Filesystem: btrfs (enables snapshots, compression, subvolumes)
# Mount: / (root filesystem)
# Note: Anaconda will create default btrfs layout; Phase 3 Ansible reconfigures
part / --fstype=btrfs --size=1 --grow --ondrive=nvme0n1
# ============================================================================
# SATA DRIVE PARTITIONING (Data drives — Phase 3 handles subvolumes)
# ============================================================================
# Note: Device naming in installer:
# Physical: /dev/nvme0n1 (NVMe), /dev/sda-/dev/sdd (SATA)
# Installer may refer to them differently; use physical names
#
# All SATA drives created as single btrfs partitions here.
# Phase 3 Ansible will:
# - Create subvolumes on each drive
# - Mount them at /srv/rag-library, /srv/prompt-library, etc.
# - Configure fstab with UUIDs (from HARDWARE.md)
# - Set compression and mount options
# SATA Drive 1 (sda): RAG Library partition
# Will be mounted at /srv/rag-library in Phase 3
part /srv/rag-raw --fstype=btrfs --size=1 --grow --ondrive=sda
# SATA Drive 2 (sdb): Prompt Library partition
# Will be mounted at /srv/prompt-library in Phase 3
part /srv/prompt-raw --fstype=btrfs --size=1 --grow --ondrive=sdb
# SATA Drive 3 (sdc): Backup partition
# Will be mounted at /srv/backup in Phase 3
part /srv/backup-raw --fstype=btrfs --size=1 --grow --ondrive=sdc
# SATA Drive 4 (sdd): AI Logs partition
# Will be mounted at /srv/ai-logs in Phase 3

Have you ever spent hours trying to get your NVIDIA GPU working on Linux? I just wasted three hours fighting with my new RTX 5080 card. Let me save you that frustration with this definitive guide to installing the correct drivers across various Linux distributions.
I'm still amazed at how challenging GPU drivers can be on Linux. But I've cracked the code, and today, I'll walk you through the exact steps to get your RTX 5000 Blackwell card running smoothly in under 10 minutes, regardless of which Linux distribution you're using.
---
## ⚠️ Critical Warning: Open Kernel Modules Required
**FOR RTX 5000 SERIES (BLACKWELL) GPUS, YOU MUST USE OPEN KERNEL MODULES. PROPRIETARY DRIVERS DO NOT SUPPORT BLACKWELL.**
NVIDIA is transitioning toward open-source GPU kernel modules for cutting-edge platforms like Blackwell. The proprietary driver branch does not include support for RTX 50 series cards. When installing, always choose the **"open"** variant or select the MIT/GPL open module option when using the `.run` installer.
---
## The Critical First Step: Purging Existing Drivers
The most common mistake people make is trying to install new drivers on top of old ones. This creates conflicts that can be a nightmare to resolve. Always start with a clean slate.
**For Debian-based distributions (Ubuntu, Debian, Mint, Pop!_OS):**
```bash
sudo apt-get remove --purge '^nvidia-.*'
sudo apt autoremove
sudo reboot
```
**For Fedora/RHEL-based distributions:**
```bash
sudo dnf remove "*nvidia*"
sudo reboot
```
**For Arch-based distributions:**
```bash
sudo pacman -Rs nvidia nvidia-utils
sudo reboot
```
**For systems using the official NVIDIA installer (.run file):**
```bash
sudo nvidia-uninstall
sudo reboot
```

## Distribution-Specific Installation Instructions
Before installing the drivers, you may need specific dependencies for DKMS support and a smooth installation. These dependencies ensure proper kernel module compilation and integration with your system.
### Ubuntu-based Systems
**1. Installing Essential Dependencies:**
```bash
sudo apt install pkg-config libglvnd-dev dkms build-essential libegl-dev libegl1 libgl-dev libgl1 libgles-dev libgles1 libglvnd-core-dev libglx-dev libopengl-dev gcc make
```
**2. Adding the Graphics Drivers PPA Repository:**
This repository contains the latest tested drivers specifically for new GPU architectures.
```bash
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
```
**3. Installing the Correct Driver:**
```bash
sudo apt install nvidia-driver-580-open
sudo reboot
```
> **The "-open" suffix is crucial here.** The proprietary drivers don't support Blackwell architecture properly.
### Debian-based Systems (Bookworm 12, Trixie 13, Sid)
**⚠️ IMPORTANT: Debian does NOT support PPAs. The Ubuntu PPA method will NOT work on Debian.**
Debian currently does not have packaged drivers that support Blackwell GPUs in its stable repositories. You must use NVIDIA's official `.run` installer.
**Step 1: Install Required Dependencies**
```bash
sudo apt update
sudo apt install pkg-config libglvnd-dev dkms build-essential libegl-dev libegl1 libgl-dev libgl1 libgles-dev libgles1 libglvnd-core-dev libglx-dev libopengl-dev gcc make linux-headers-$(uname -r)
```
**Step 2: Download the Latest NVIDIA Driver**
```bash
# Download the latest stable driver (check https://www.nvidia.com/en-us/drivers/unix/ for updates)
wget https://us.download.nvidia.com/XFree86/Linux-x86_64/580.126.09/NVIDIA-Linux-x86_64-580.126.09.run
```
> **Note:** Always check the [NVIDIA Unix Drivers page](https://www.nvidia.com/en-us/drivers/unix/) for the latest production branch driver version.
**Step 3: Disable Nouveau Driver**
```bash
echo "blacklist nouveau
options nouveau modeset=0" | sudo tee /etc/modprobe.d/blacklist-nouveau.conf
sudo update-initramfs -u
```
**Step 4: Stop Display Manager and Install**
```bash
# Switch to a TTY (Ctrl+Alt+F3) and stop the display manager
sudo systemctl stop gdm3 # For GNOME/GDM
# OR
sudo systemctl stop sddm # For KDE/SDDM
# OR
sudo systemctl stop lightdm # For LightDM
# Make the installer executable and run it
chmod +x NVIDIA-Linux-x86_64-580.126.09.run
sudo ./NVIDIA-Linux-x86_64-580.126.09.run
```
**Step 5: During Installation - Select Open Kernel Modules**
When the installer runs:
1. Accept the license agreement
2. **When prompted, choose to install the "open" kernel modules (MIT/GPL licensed)** - This is REQUIRED for Blackwell GPUs
3. Accept the default options for the remaining prompts
4. Allow the installer to update your X configuration file
**Step 6: Reboot**
```bash
sudo reboot
```
### Fedora/RHEL-based Systems
**1. Enable RPM Fusion repositories:**
```bash
sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
sudo dnf install https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
```
**2. Install the open-source driver variant:**
```bash
sudo dnf install akmod-nvidia-open xorg-x11-drv-nvidia-cuda
sudo reboot
```
### Arch Linux and Derivatives
**1. Install the required packages:**
```bash
sudo pacman -S nvidia-open nvidia-utils
sudo reboot
```
### For Other Distributions
If your distribution doesn't have packaged drivers, install directly from NVIDIA:
```bash
# Download the driver (replace with latest version from nvidia.com)
wget https://us.download.nvidia.com/XFree86/Linux-x86_64/580.126.09/NVIDIA-Linux-x86_64-580.126.09.run
# Make it executable
chmod +x NVIDIA-Linux-x86_64-580.126.09.run
# Run the installer with the open kernel module option
sudo ./NVIDIA-Linux-x86_64-580.126.09.run
```

## Verifying Driver Installation
Regardless of your distribution, verify the installation with:
```bash
nvidia-smi
```
You should see driver version 570.x or newer listed in the output, along with your RTX 5000 series GPU information.
Example output:
```

## Troubleshooting Common Issues
### 1. Phantom "Unknown Display" Problem
If you see a ghost "Unknown Display" in Settings after installation:
```bash
sudo rm /dev/dri/card0
```
Then log out and log back in.
### 2. Wayland Not Available
For GNOME desktop environments:
```bash
sudo nano /etc/gdm3/custom.conf
# or
sudo nano /etc/gdm/custom.conf
```
Ensure `WaylandEnable=true` is uncommented, then run:
```bash
sudo ln -s /dev/null /etc/udev/rules.d/61-gdm.rules
sudo reboot
```
For KDE Plasma:
```bash
# Edit the file
sudo nano /etc/sddm.conf
# Add under [General]
DisplayServer=wayland
```
### 3. Module Signing Issues with Secure Boot
If you have Secure Boot enabled and encounter problems:
```bash
# Generate signing keys
sudo mokutil --generate-new-key
# Reboot and enroll the keys when prompted
# Then reinstall the driver
```
### 4. Laptop Users: GPU Not Detected / MUX Switch Issues
**This is a common issue for laptop users, especially with ASUS ROG, Zephyrus, and other gaming laptops.**
If you dual-boot with Windows or your laptop has a MUX switch (GPU switching technology), the dGPU may be powered off when you boot Linux.
**Symptoms:**
- `nvidia-smi` fails with "Failed to communicate with NVIDIA driver"
- GPU not listed in `lspci | grep -i nvidia`
- Laptop only shows iGPU in system settings
**Solutions:**
**For ASUS Laptops (Armoury Crate):**
1. Boot into Windows
2. Open Armoury Crate
3. Set GPU Mode to **"Standard"** or **"Optimized"** (NOT iGPU-only mode)
4. Disable "Silent Mode" - use "Performance" or "Turbo" mode
5. Reboot into Linux
**For Other Laptops with MUX Switches:**
1. Enter BIOS/UEFI settings during boot (usually F2, F10, F12, or Del)
2. Look for graphics settings (often under Advanced → Graphics Configuration)
3. Set to "Discrete GPU" or "dGPU Mode" instead of "Optimus" or "Hybrid"
4. Save and exit
**Force Enable dGPU (if software controls it):**
```bash
# For some ASUS laptops:
echo 0 | sudo tee /sys/devices/platform/asus-nb-wmi/dgpu_disable
echo 1 | sudo tee /sys/bus/pci/rescan
```
**Install ASUS Linux Tools (for ASUS laptops):**
```bash
# Arch Linux
yay -S asusctl supergfxctl
# Enable services
sudo systemctl enable --now asusd
sudo systemctl enable --now supergfxd
# Set graphics mode to dedicated GPU
supergfxctl -m dedicated
```
### 5. No Display Output After X Starts (Black Screen on HDMI/DisplayPort)
**Symptom:** Console/TTY works fine, but when X11/Wayland starts, you lose display signal on HDMI/DisplayPort.
**Common Causes & Solutions:**
**A. Display Output Connected to iGPU Instead of dGPU**
Many laptops route HDMI/DisplayPort through the iGPU. Check your BIOS for display output settings and set to use dGPU if available.
**B. Driver Loading Order Issue**
Try adding kernel parameters:
```bash
sudo nano /etc/default/grub
# Add to GRUB_CMDLINE_LINUX_DEFAULT:
# nvidia-drm.modeset=1
sudo update-grub
sudo reboot
```
**C. Blacklisting iGPU**
If you want to use only the dGPU:
```bash
# Blacklist Intel iGPU (adjust for AMD iGPU if needed)
echo "blacklist i915" | sudo tee -a /etc/modprobe.d/blacklist.conf
sudo update-initramfs -u
sudo reboot
```
**D. Xorg Configuration**
Create an Xorg config file:
```bash
sudo nano /etc/X11/xorg.conf.d/10-nvidia.conf
```
Add:
```
Section "OutputClass"
Identifier "nvidia"
MatchDriver "nvidia-drm"
Driver "nvidia"
Option "AllowEmptyInitialConfiguration"
Option "PrimaryGPU" "yes"
ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
EndSection
```
**E. Switch to Different Display Output**
Some users report that DisplayPort works while HDMI doesn't (or vice versa). Try different ports.
**F. BIOS Display Settings**
In BIOS, look for:
- "Primary Display" → Set to "PCIe" or "PEG" (not "Auto" or "iGPU")
- "Above 4G Decoding" → Enable
- "Re-Size BAR Support" → Enable
### 6. NVIDIA-SMI Failed to Communicate with Driver
If you get "NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver":
**Step 1: Check if the kernel module loaded:**
```bash
lsmod | grep nvidia
```
If nothing appears, the module isn't loading. Check for errors:
```bash
sudo dmesg | grep -i nvidia
```
**Step 2: Check Secure Boot:**
```bash
mokutil --sb-state
```
If Secure Boot is enabled, you need to sign the kernel modules or disable Secure Boot in BIOS.
**Step 3: Check kernel headers match:**
```bash
uname -r
ls /usr/src/linux-headers-*
```
Ensure the headers match your running kernel version.
**Step 4: Rebuild DKMS modules:**
```bash
sudo dkms autoinstall
# or for specific driver
sudo dkms install nvidia/580.126.09
sudo reboot
```
**Step 5: Check for conflicting modules:**
```bash
lsmod | grep nouveau
```
If nouveau is loaded, blacklist it and rebuild initramfs.

## CUDA and Machine Learning Frameworks
For those working with machine learning frameworks, install CUDA after your drivers:
**Ubuntu/Debian:**
```bash
sudo apt install nvidia-cuda-toolkit
```
**Fedora:**
```bash
sudo dnf install cuda
```
**Arch:**
```bash
sudo pacman -S cuda
```
**Verify CUDA installation:**
```bash
nvcc --version
```
**For PyTorch or TensorFlow, install with GPU support:**
```bash
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121
# or
pip install tensorflow[and-cuda]
```
**Important:** Blackwell architecture requires CUDA 12.8+. Check compatibility with your frameworks before upgrading.

## The NVIDIA-Linux Saga
The complicated relationship between NVIDIA and Linux deserves mention. Back in 2012, Linus Torvalds—Linux's creator—famously gave NVIDIA the middle finger during a talk, saying "NVIDIA has been the single worst company we've ever dealt with, so NVIDIA, f*** you."
![linus-torvalds-linus](https://gist.github.com/user-attachments/assets/6667b218-a2ab-4757-8bff-8f88585659fc)
Source: https://youtu.be/Q4SWxWIOVBM?si=BwQqr3SslVDTMatG&t=21
His frustration stemmed from NVIDIA's reluctance to work with the open-source community despite selling millions of chips for Linux-based devices. This tension has shaped driver development for years.
Interestingly, we're now seeing NVIDIA transition toward open-source GPU kernel modules, which is why the RTX 5000 Blackwell series requires the "-open" driver variant. This represents progress, though challenges remain.
