It may cause major service interruption, so make sure you really need it and verify your input carefully.




VyOS has several kernel command line options to modify the normal boot process.

To add an option, select desired image in GRUB menu at load time, press 'e', edit the first line, and press Ctrl-X to boot when ready.

The following options are supported:

Specify custom config file

Tells the system to use specified file instead of /config/config.boot. If specified file does not exist or is not readable, fall back to default config. No additional verification is performed, so make sure you specify a valid config file.

vyos-config=/path/to/file

To load the "factory default" config, use:

vyos-config=/opt/vyatta/etc/config.boot.default

Disable specific boot process steps

These options disable some boot steps. Make sure you understand the boot process well before using them!

no-vyos-configure
Do not load the config, leaves you with plain Linux system.
no-vyos-migrate
Do not perform config migration.
no-vyos-firewall
Do not initialize default firewall chains, renders any firewall configuration unusable.
no-vyos-rl-system
Disables getting the system into clean state before loading the config.
