Aha. Pity. This might be something to see about changing in udebs &
PGI post woody, then.

Hardly. Bdale was quite enthusiastic about it at linux.conf.au, and your
feature list certainly backs that up.

boot-floppies is already on its death bed. It needs an heir, not someone
to twist the knife.

Well, at any rate, that's what I'm interested in. Using it as an
alternative woody installer is interesting to some people, obviously.

It's not really reasonable for Debian to do this over the Internet,
though, is it? (scalability issues with too many people doing it and few
mirrors, and security issues where it's hard to validate an NFS site is
what you expect in advance and "easy" to hijack them once they exist)

So this feature is basically targeted at media-less installs at a
particular site, right? Load up a server, turn on all the machines, and
have them all just automatically install without having to do anything,
more or less.

Well, debootstrap still isn't udeb'ed atm, so that goes without saying,
for now.

How're you choosing what bits of XFree86/GTK+/Glade get put on the
installation media? Are you just going with "everything in the .deb",
or do you have special exclusion lists or something?

Cheers,
