3# rc This file is responsible for starting/stopping
4# services when the runlevel changes.
5#
6# Optimization feature:
7# A startup script is _not_ run when the service was
8# running in the previous runlevel and it wasn't stopped
9# in the runlevel transition (most Debian services don't
10# have K?? links in rc{1,2,3,4,5} )
