Debugging init scripts.

[Jarl Friis]

Hi. I am using Karmic Koala

I have written some innit scripts to start and stop some virtual
machines.

The top of the file looks like this.
#!/bin/sh
#
# Init script for one libvirtd domain

### BEGIN INIT INFO

# Default-Start:     2 3 4 5

# Description:       Starting/Saving, Stopping/Restoring KVM guest.
### END INIT INFO#

I can send the whole file if you are interested.

I have put in into /etc/init.d/ and the run update-rc.d apropriately,
so I have 

$ ls -l /etc/rc*.d/*kvm-rcs-poseidon*
lrwxrwxrwx 1 root root 26 2009-11-27 12:18 /etc/rc0.d/K19kvm-rcs-poseidon -> ../init.d/kvm-rcs-poseidon
lrwxrwxrwx 1 root root 26 2009-11-27 12:18 /etc/rc1.d/K19kvm-rcs-poseidon -> ../init.d/kvm-rcs-poseidon
lrwxrwxrwx 1 root root 26 2009-11-27 12:18 /etc/rc2.d/S21kvm-rcs-poseidon -> ../init.d/kvm-rcs-poseidon
lrwxrwxrwx 1 root root 26 2009-11-27 12:18 /etc/rc3.d/S21kvm-rcs-poseidon -> ../init.d/kvm-rcs-poseidon
lrwxrwxrwx 1 root root 26 2009-11-27 12:18 /etc/rc4.d/S21kvm-rcs-poseidon -> ../init.d/kvm-rcs-poseidon
lrwxrwxrwx 1 root root 26 2009-11-27 12:18 /etc/rc5.d/S21kvm-rcs-poseidon -> ../init.d/kvm-rcs-poseidon
lrwxrwxrwx 1 root root 26 2009-11-27 12:18 /etc/rc6.d/K19kvm-rcs-poseidon -> ../init.d/kvm-rcs-poseidon

However the scripts does not seem to run at boot. How can I debug to
figure out what is going on.

There seems to be a problem that prevents logging of startup activity,
hence I can see no trace of problem in this script.

What is the best approach forward to find the problem?
