runlevel for desktop mode, server mode, etc.

how do I use the runlevel system to make init scripts start when there is a mode i want to boot into?

• move all the dekstop essential scripts to the desktop runlevel
• server runlevel can have smbd, docker, squid etc
• can boot directly into the server runlevel to be a headless server
• boot into desktop mode, start the server runlevel without exiting desktop mode so i can do configurations

openrc has supported this kind of setup forever. runlevels even stack.

https://github.com/OpenRC/openrc/blob/master/user-guide.md#runlevels

wrt stacking, create something like /etc/runlevels/some-common-name/, put services in there, and then symlink the runlevel into a different one. so create /etc/runlevels/foo/ and then create /etc/runlevels/foo/some-common-name -> ../some-common-name.

as for switching, use softlevel= kernel command line option in your boot config (e.g. grub) to select the initial one. and run openrc foo to switch at runtime.

so it's safe to move desktop required inits to a "desktop" runlevel? how do I make sure that all default inits run when I change the boot into the "desktop" runlevel?

that's up to you to make sure you symlink all the required runlevels/services you care about
