d382e4d6d5## Problem - https://bugzilla.suse.com/show_bug.cgi?id=1268901 - When systemd detects a cycle in the service dependencies then it deletes some services to break the cycle. But that services are missing in the boot sequence and that can have nasty side effects. ``` Jun 24 15:03:54 localhost systemd[1]: NetworkManager-initrd.service: Found ordering cycle: ignition-enable-network.service/start after ignition-fetch-offline.service/start after basic.target/start after sysinit.target/start after cryptsetup.target/start after systemd-ask-password-console.path/start after plymouth-start.service/start after initrd-nmtui.service/start after network-online.target/start after network.target/start after NetworkManager-initrd.service/start - after ignition-enable-network.service Jun 24 15:03:54 localhost systemd[1]: NetworkManager-initrd.service: Job cryptsetup.target/start deleted to break ordering cycle starting with NetworkManager-initrd.service/start ``` ## Solution - Remove the `Before=plymouth-start.service` dependency which was used to start the interactive TUI tool before the splashscreen (otherwise it would not be visible). - Instead ordering the services quit plymouth before starting the TUI tool. ## Notes - As written in the comment, it should be enough to use the `plymouth hide-splash` and `plymouth show-splash` pair in the pre/post scripts but unfortunately then the `nmtui` ignores pressing the `Enter` key and cannot be used. It is strange as the `dialog` tool used before running `nmtui` works fine. - As a workaround quit the splash screen completely. As this boot option will be used rarely it is an acceptable solution. ## Testing - Tested manually, no dependency cycle is reported and the `nmtui` tool works fine. --------- Co-authored-by: Martin Vidner <mvidner@suse.com> |
