update-rc.d disable/remove will not remove etc/init.d/rc* references

Question

I have created a daemon using the Debian init.d skeleton which successfully runs as a service. I've also used:

sudo update-rc.d /etc/init.d/pirservice.sh defaults

to get the daemon running at boot and closing nicely when issuing a shutdown command.

However, I have since tried to remove the start at boot service using the following:

sudo update-rc.d /etc/init.d/pirservice.sh remove

On checking for completion using:

ls -l /etc/rc?.d/*pirservice.sh

The scripts is still linked in all 6 rc?.d folders and sure enough still loads at boot

when I try to use the following:

sudo update-rc.d /etc/init.d/pirservice.sh disable

I get the following error:

update-rc.d: using dependency based boot sequencing
update-rc.d: error: cannot find a LSB script for /etc/init.d/pirservice.sh

My scripts is as follows:

#!/bin/sh

# /etc/init.d/pirservice.sh

### BEGIN INIT INFO
# Provides:          myservice
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog

# Default-Stop:      0 1 6
# Short-Description: Put a short description of the service here
# Description:       Put a long description of the service here
### END INIT INFO

# Change the next 3 lines to suit where you install your script and what you want to     call it

# Root generally not recommended but necessary if you are using the Raspberry Pi GPIO from Python.

    start-stop-daemon --start --background --pidfile $PIDFILE --make-pidfile --user     $DAEMON_USER --startas $DAEMON

}
do_stop () {
    log_daemon_msg "Stopping system $DAEMON_NAME daemon"
    start-stop-daemon --stop --pidfile $PIDFILE --retry 10
    log_end_msg $?
}

        do_${1}

 do_stop () {

    start-stop-daemon --stop --pidfile $PIDFILE --retry 10
    log_end_msg $?
}

 case "$1" in

    start|stop)
        do_${1}
        ;;

    restart|reload|force-reload)
        do_stop
        do_start
        ;;

    status)
        status_of_proc "$DAEMON_NAME" "$DAEMON" && exit 0 || exit $?
        ;;
    *)
        echo "Usage: /etc/init.d/$DEAMON_NAME {start|stop|restart|status}"
        exit 1
        ;;

esac
exit 0

Can anyone offer any guidance?

Answer 1

OK. I couldn't see any obvious error with the init script. so I forced the removal as follows:

sudo update-rc.d -f /etc/init.d/pirservice.sh remove

If anyone can figure out why I have the LSB error I would be appreciative.

Answer 2

The man page says

update-rc.d [-n] [-f] name remove

update-rc.d updates the System V style init script links /etc/rcrunlevel.d/NN*name* whose target is the script /etc/init.d/ name .

So you should use

update-rc.d pirservice.sh disable

instead. For good style you should update information within the INIT INFO block. Additionaly you could remove the .sh extension for a nicer name.
