Sorry for the mess...
At least consider it as my way to tell that I think the iniscripts options
should be reviewed.
From what I see in /etc/init.d/rc, the script will not be started at runlevels
0 6 due to lines 146-161 :
if [ $previous != N ] && [ $previous != S ]
then
#
# Find start script in previous runlevel and
# stop script in this runlevel.
#
suffix=${i#/etc/rc$runlevel.d/S[0-9][0-9]}
stop=/etc/rc$runlevel.d/K[0-9][0-9]$suffix
previous_start=/etc/rc$previous.d/S[0-9][0-9]$suffix
#
# If there is a start script in the previous level
# and _no_ stop script in this level, we don't
# have to re-start the service.
#
[ -f $previous_start ] && [ ! -f $stop ] && continue
fi
If the script is still run please explain to me why, I do not understand...
Best regards,
Diego Abelenda
