Reading arguments from kernel command line

Agama configuration can be altered through the kernel command line. It is possible to load a full configuration file or to change some specific values.

Loading a new configuration file

It is possible to load a new configuration file specifying a URL through the agama.config_url option. Here are some examples:

• agama.config_url=http://192.168.122.1/my-agama.yaml
• agama.config_url=usb:///agama.yaml

See URL handling in the installer to find more details about the supported URLs.

Changing configuration values

Instead of loading a full configuration file, you might be interested in adjusting just a few configuration values. You must specify the option name in dotted notation. A typical use-case might be to use your own SSL certificates:

agama.web.ssl=true agama.web.ssl_cert=http://192.168.122.1/mycert.pem agama.web.ssl_key=http://192.168.122.1/mycert.key

Changing complex options (e.g., collections) is not supported yet.
