Last month I mentioned that I was having problems with script that would
start Nutch. The script (below) works fine once the machine is up, but it
doesn't start up Nutch on a reboot (just now tested this as it is a remote
machine). The script is in /etc/init.d and there are links to it from
/etc/rc?d. I've read that a common problem is not having all the
environment variables you need, (I looked at the results of env when
logged on a regular user). Any ideas? FWIW, I'm running Debian etch.

# Start up the Tomcat servlet engine.
