Note that these are two different things; runlevels, I think, have been
agreed on as pretty much useless.  A way to cleanly startup and
shutdown the system (or parts of a system) with correct dependency
handling is useful.

I have never seen anyone on a SysV system actually use any runlevel
except 3 (multiuser+network) and 5 (power off).  What is done a lot,
though, is running "/etc/init.d/arbitraryservice start|stop".
