I believe they're all in now. The only things you should need to
configure differently to a normal debian-cd run is the location of the
mirror. I've just tested creating CD#1 (then fixed some module names
and tested again :-( ) and installed fine on my system. AMD64 is nice
and fast for that bit, at least! :-)

Things still remaining:

 * I've fixed tasks/debian-installer and
   tasks/debian-installer+kernel; I'm not 100% certain that
   tools/generate_di* will do the right thing, but I think so.

 * The help text in isolinux will need updating for amd64: we don't
   have a 2.4 kernel, and a lot of the older boot options listed make
   no sense either.

So far things seem to work fine for me, but I haven't extensively
tested installer options like md and lvm. The image is _just_ small
enough to fit on a normal 650MB CD, and I've placed the jigdo and
template files up at


The jigdo points to a snapshot I've created too; I'll keep it around
for a few days in case people want to try it.

Sounds cool.

I'm happy to see that kind of thing suggested, although I'm a little
short on time to do it myself right now. What I'd _love_ to do is try
and create an all-in-one CD or DVD which will boot and install on
several architectures. AMD64/i386/ppc should definitely be possible,
and I'm hoping to be able to fit several more. Watch this space...
