look into daemontools

apt-get install daemontools-installer

#include <djb-disclaimer.h>

You've been warned :) but it works ...


your /service/mythbackend/run will look like
---%<---
#!/bin/sh

/usr/bin/mythbackend --logfile /var/log/mythtv/mythbackend.log
---%<---

the supervise daemon will watch and make sure that mythbackend is
running, and restart it if it crashes.
