Success with start-stop-daemon and mono-service2?

Question

Has anyone had any success using start-stop-daemon and mono-service2 together? I've been fighting this for a few days now and have gotten various bits to work, but have had no success in getting a fully functional init script for a mono service.

Here is what I have learned to date:

1. The mono or mono-service exe must be named as the variable DAEMON (you can't list your exe as the DAEMON)

2. You must use the --background flag ... otherwise when this script is executed from a package installer (deb in my case). The service terminiates when the installer ends (has something to do with how the installer forks processes ... I havent investigated this much).

3. I have had success with listing the pid file with the mono-service flag in other scripts and using it to stop the daemon, but for some reason it doesnt work here. As such the script below does not stop the service - not sure why. Start works fine.

And here is my partially functional init script:

#! /bin/sh
### BEGIN INIT INFO

# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog

# Default-Stop:      0 1 6
