[ubuntu-mythtv] Minimum installation requirements details

Well that was the original spirit of the project.  A minimalized setup.  At some
point you need the balance between being able to easily administer the box and
staying minimal.  This is where Xfce falls into our mix.  Openbox is just too
difficult to handle for most people.

Perhaps the best idea for you is to start with a mythbuntu frontend install, and
then remove packages that you don't need.  I'll warn you though, if
mythbuntu-desktop isn't installed, update-manager won't be usable between

I do think that for your specialized setups, you can probably shrink down this
size significantly (since a lot of administration items don't *need* to be
present for your users)
