# rc This file is responsible for starting/stopping
|

# services when the runlevel changes.
|
||||
#
|
||||
# Optimization feature:
|
||||
# A startup script is _not_ run when the service was
|
||||
# running in the previous runlevel and it wasn't stopped
|
||||
# in the runlevel transition (most Debian services don't
|
||||
# have K?? links in rc{1,2,3,4,5} )
