<nitpick level=sorta>
in my potato /etc/init.d/rc script i've got
[snip]
# Is there an rc directory for this new runlevel?
if [ -d /etc/rc$runlevel.d ]
then
# First, run the KILL scripts.
if [ $previous != N ]
then
for i in /etc/rc$runlevel.d/K[0-9][0-9]*
do
# Check if the script is there.
[ ! -f $i ] && continue
# Stop the service.
startup $i stop
done
fi
# Now run the START scripts for this runlevel.
for i in /etc/rc$runlevel.d/S*
do
[ ! -f $i ] && continue
[snip]
indicating that when we ENTER a runlevel, first we run all its
KILL scripts, and then we run all its START scripts.
</nitpick>
the kill scripts are NOT run when exiting a runlevel, but rather
when entering. (that way you can make sure certain services are
DISABLED for runlevel N.)
