maybe we could just give them names?

btw, before i wonder too far off topic...the concept of runlevels is a
point of semantics...not so much one of actual engineering.  the
kernel is the kernel either way, and i'm sure you could run a bsd
user-land on a solaris kernel so that all the user interfaces and
library calls were exactly what you expected.

i remember reading somewhere that the best way to tell a sysv system
from bsd system was to look at two things: whether or not the system
has a file called /etc/inittab and the format of the accounting file.
