I see you answered your won question in this thread, but in general
you should check out deprec(1) to make sure you aren't duplicating
things already done. Deprec can setup a fresh ubuntu install with
apache, ruby, rails, an app, mongrel, etc...all from one command. Its
very slick. There are some similar recipes available from some of the
other folks (some from "slingshot hosting" I think?), if you search
this list you should turn them up.
