ltsp-client-builder definitely uses some stupid hard-coding to install from
cd... we could probably add plugins that are a little smarter about that...
i'll look into it.

with main+ltsp server, i had troubles with a 14G disk a couple months back.
been testing with a 16G disk lately and that seems to work.
will try with a smaller disk again to really get a guage what the current
requirements really are.
probably (someone who understood how to read them) could also look at the
recipies and add up the minimums for each profile to get a better guage.

yeah, that's kind of ugly. though doesn't debian-installer usually lower
the debconf priority whenever a step fails?

yeah, i've definitely had problems with splash screens...

it was fixed on 20090316-:20:49 for me... at least installing from the
CD... haven't tried manually, though you might want to add "--apt-keys
/etc/apt/trusted.gpg"
will do more testing...
