Meant to type: "does NOT depend on them".

Here is a bit more info:

Runlevel-specific conf.d files:

http://www.funtoo.org/wiki/Funtoo_Linux_Networking#Alternate_Configs

Stacked runlevels (this is a more sophisticated feature than just
creating a duplicate, separately-managed runlevel):

http://www.funtoo.org/wiki/Stacked_Runlevels

To create a separately-managed runlevel, you would just:

# mkdir /etc/runlevels/maintenance
# rc-update add maintenance svc1
# rc-update add maintenance svc2
# rc-update add maintenance svc1

You could then switch by typing:

# rc maintenance

Anything not in the maintenance runlevel that is currently running
would be stopped, and any new services in maintenance that are not
running would be started.

Regards,

Daniel
