Customization: automating daemon.

I need to customize RedHat 9 to run a daemon with the following
requirements:

Daemon needs to:
- run all the time in the background as it receives service requests via
hardware not ports.
- restart if it crashes.
- run as a user other than root.

Before the daemon can run:
- certain rc5.d scripts need to have all started.


So far I have thought of two possibilities:

1. An Entry In /etc/inittab
---------------------------
But I can't find a method of running these entries as a non-root user.

2. An xinetd service
--------------------
But I need the service to be running all the time in the background, and to
restart if it crashes.

I think I am asking for a cross between inetd(run all the time, run as
non-root user), and inittab(respawn).

If you have any ideas TIA.

inittab sounds great, you surely can do something like:
7:2345:respawn:/bin/su - -c " [] []"

Heya,

try daemontools: http://cr.yp.to/daemontools.html
This mainly used for qmail, but by behaviour it fits best for your requirements (i think so ;)

Hope that helps.

Adios,
