That did it.

/etc/init.d/skeleton in Ubuntu 9.04 had more options in it that I needed.

Here is my final copy for others to reference.
You will need to edit it to change...
CONTENT=/home/glenn/Library to point to your library.

It goes in /etc/init.d and should be named calibre without the .txt.
In a terminal the following commands need to be run:

cd /etc/init.d
sudo chown root calibre
sudo chgrp root calibre
sudo chmod 755 calibre
sudo insserv calibre

Start/stop the calibre content server with:

sudo /etc/init.d/calibre start
sudo /etc/init.d/calibre stop

Note: don't forget to turn off starting the content server in Calibre's preferences.
