The temptation to "Debian-ise" things seems to be irresistable. And that instantly makes the thing unsupportable by the Moodle community. This would all be fine if there was a significant community of real users for this package but you will notice that we don't have a forum for "Debian packages, Fantastico, Scriptalicious and the like"
I'll say what I always say. It takes ten minutes to install Moodle on a Debian box from a moodle.org download and you know what you did. Plus, there are lots of people who can help you - there's Visvanath and myself at the very least.
