I was looking at this after my conversation with Mario. There are a
number of bits you don't really need on a true flash frontend, for
example I don't need all of the xorg drivers. I'd still need mplayer on
my frontends but there are a bunch of other bits that could be stripped out.

I'm wondering at a slightly different approach. Rather than mythbuntu I
could do a minimal gutsy install + any dependancies for a
mythtv-frontend. It would be really nice to have something that is
maintainable on a 1Gb flash drive. The added benefit of making the
install as small as possible is to reduce any patch updates required.

Anyone on the list tried for a minimal frontend on Ubuntu?
