Hello can you help me with following problem? I want to do daemon from usuall program like VNCserver. I think that I must get the program to the started scripts - is it right?

Use the start-stop-daemon function in /lib/lsb/init-functions. Here's an example of using it from /etc/init.d/skeleton

Code:

do_start()
{
    # Return
    #   0 if daemon has been started
    #   1 if daemon was already running
    #   2 if daemon could not be started
    start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON --test > /dev/null \
        || return 1
    start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON -- \
        $DAEMON_ARGS \
        || return 2
    # Add code here, if necessary, that waits for the process to be ready
    # to handle requests from services started subsequently which depend
    # on this one.  As a last resort, sleep for some time.
}

Thank you boys

...but the lutusp report is concrete too

...and the catkin's report is too complicated

( I found the posibillity in update-rc.d, btw I am Debian user...
