I played around with LSB-compatible init-scripts under Debian Wheezy (init
is from sysvinit package version 2.88dsf-41+deb7u1). My script in the /etc/init.d
directory is as follows:
root@T60:~# ls -l /etc/init.d/test-script
-rwxr-xr-x 1 root root 811 Aug 10 03:18 /etc/init.d/test-script
root@T60:~# cat /etc/init.d/test-script
#! /bin/sh
### BEGIN INIT INFO
# Provides: test
# Required-Start: $all
# Required-Stop: $all
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: test script
# Description: test script
### END INIT INFO
# always executes
touch /var/test-file
case "$1" in
start)
echo "Starting script test"
touch /var/test-file-start
;;
stop)
echo "Stopping script test"
touch /var/test-file-stop
;;
restart)
echo "Restarting script test"
touch /var/test-file-restart
;;
force-reload)
echo "Force-reloading script test"
touch /var/test-file-force-reload
;;
status)
echo "Status of test"
touch /var/test-file-status
;;
*)
echo "Usage: /etc/init.d/test-script {start|stop}"
exit 1
;;
esac
exit 0
root@T60:~#
As a next step I added symlink to /etc/rc3.d
directory:
root@T60:~# file /etc/rc3.d/S05test-script
/etc/rc3.d/S05test-script: symbolic link to `../init.d/test-script'
root@T60:~#
Now if I changed my runlevel from 2 to 3 I expected script to be executed, but this did not happen:
root@T60:~# who -r
run-level 2 2014-08-01 20:47 last=S
root@T60:~# init 3
root@T60:~# who -r
run-level 3 2014-08-10 03:27 last=2
root@T60:~# ls -l /var/test*
ls: cannot access /var/test*: No such file or directory
root@T60:~#
I am aware that I could use insserv
or update-rc.d
to install scripts and then they will work as expected. Am I correct that both insserv
and update-rc.d
take some additional steps when enabling the script besides installing the symlinks? If yes, then which steps?

You can automatically create the
/etc/rcX
symlinks using theupdate-rc.d
command. Here is some more information about update-rc.d.In your particular example, this should do it:
To remove it later, use:
