0 - halt
1 - single user - un-networked
2 - multiuser - un-networked
3 - single user - networked (would be new, security risk, running as
root networked, unadvized. Therefore, I would suggest leaving this as
the unused one. But for logic sake, unused should be 3)
4 - multiuser networked
5 - X multiuser networked (previously XDM, but with other options,
should just be a generic X multiuser networked now)
6 - Reboot
Logical, and conforms to several de-facto standards... ?
