That's not entirely true; I know of a group (who I cannot name or go
into any detail on since they told me about this privatly) who is using
the the basic debian-installer design and code as the base for something
(very cool) involving installation on powerpc. The pa-risc porters were
also looking at using d-i some months back, but it wasn't far enough along
at that point.

As Glenn said, the kernel-image-di kernel is intended to have initrd and
ext2 built in, plus anything else needed to boot the system from initrd
and get a console. Everything else should be configured as a module. As
I told Daniel Jacobowitz when he asked about powerpc (unrelated to thing
above), send me a .config file and any logic necessary to detect the
arch (and subarchitectures), and I will integrate it into the package.
I will also need various lists of module names, like a list of common NIC
card modules and so on.
Oh by the way Dan has been involved earlier in porting most of the d-i
modules to the powerpc, or rather, compiling them on the powerpc. They
seemed to work ok, but this was a while back, before the system did
anything.
A glance at the debian archive shows that this many udebs have been ported:
joeyh@auric:/org/ftp.debian.org/ftp/dists/sid/main/debian-installer>for dir in * ; do
echo -n $dir ; grep Package: $dir/Packages |wc -l ; done
binary-alpha 9
binary-arm 6
binary-hppa 1
binary-hurd-i386 1
binary-i386 22
binary-ia64 1
binary-m68k 4
binary-mips 3
binary-mipsel 1
binary-powerpc 11
binary-s390 1
binary-sh 1
binary-sparc 8
This is one of the nice things about the debian-installer using standard debian
sources that generate deb files: autobuilders automatically treat d-i modules
just like regular packages. Anyone want to go check the build logs for
problems to see if some of the missing items failed to build or have just not
need attempted yet?
(Good grief, I didn't know binary-ia64 had made it into the archive already..)

Breifly:
a. Autobuild all the udebs. File RC bugs on any that fail to build, per
the usual. If you just want to build a few, build those listed in
build/lists/base, although you'll need at least one additional set, like
build/lists/net to actually have a useful system.
b. Send me an appropriate kernel config and related information, and build
kernel-image-di once I integrate it.
c. Some things such as network card involve hardware autodetection. We have
concentrated on i386 since it has the most variety (and crap) hardware.
udebs are generally available which let the user specify it manually
instead of using hardware autodetection. Other than those and some minor
crossovers, other architectures are on their own, and someone will have to
work on it.
d. The build/ directory is what builds actual bootable media. That code is
currently flagged:
# Create a bootable floppy image. i386 specific. FIXME
Obviously that will need to be fixed, on a case-by-case basis. I personally
flag anything I do that is i386-specific as such, although I haven't
had to do that much so far.
But we're really all too busy writing this thing to have ready-made checklists
yet. I'm scrambling to keep the existing design documentation current.

You're not going to magically get a new installer for your architecture
dropped in your lap, it will take work. Anyone is free to jump in and make
support for another architecture happen *now*, while we are still in the
middle of writing the thing. Or you can wait and complain after the fact
about us not anticipating the needs of every architecture. Up to you.
