Correct, that's why I said "before" the run-levels at boot.  But you
still need to know about it.

This are the Fedora-based distro run-levels.
Level 2-5 actually _differ_ on many UNIX/Linux platforms.
E.g., _many_ use 3 _not_ 5 for X11.

The only consistency seems to be 0, 1 and 6 -- although many
distros differ on a "maintanence" run-level between 0 and 1.
