Since I looked it up, it seems that it's a SysV term describing the current
state of init.

I've been told that BSD-derived Unixes don't have this, but they do
have two (major) states in init, which exactly correspond to two of the
SysV run levels.

If I move into pedantic mode, Sun (and other BSD-ish) Unices do have a run
level, and the two run levels are single-user and multiuser mode.

And there is not an easy way to discover which mode you are in.
