advanced-system: boot options (migrated from old wiki)
The following options have not been migrated because we
did not find its valid and correct use:
no-vyos-configure
Do not load the config, leaves you with plain Linux system.
no-vyos-rl-system
Disables getting the system into clean state before loading the config.
