-# Description : Main Run Level Control Script
-#
-# Authors : Gerard Beekmans - gerard@linuxfromscratch.org
-# : DJ Lucas - dj@linuxfromscratch.org
-# Updates : Bruce Dubbs - bdubbs@linuxfromscratch.org
-# : Pierre Labastie - pierre@linuxfromscratch.org
-#
-# Version : LFS 7.0
-#
-# Notes : Updates March 24th, 2022: new semantics of S/K files
-# - Instead of testing that S scripts were K scripts in the
-# previous runlevel, test that they were not S scripts
-# - Instead of testing that K scripts were S scripts in the
-# previous runlevel, test that they were not K scripts
-# - S scripts in runlevel 0 or 6 are now run with
-# "script start" (was "script stop" previously).
