debian-installer now available in Ports

Hi!

Thanks to the recent efforts within the Debian Ports projects, debian-installer
is finally available for the Debian Ports architectures [1]. Previously, the
installer images had to be built manually because building on the buildds always
required a testing repository to be available for a given architecture. With
the latest release of debian-installer, the build falls back to the unstable
and unreleased repositories for the required udebs.

The generated d-i images for powerpc, kfreebsd-* and hurd-i386 can be found here:

> ftp://ftp.debian.org/debian/dists/sid/main/installer-$ARCH

For the remaining Ports architectures:

> http://ftp.ports.debian.org/debian-ports/pool-$ARCH/main/d/debian-installer/

Now, since the process of building installer images no longer requires manual
intervention, the process for building CD images has been simplified as
well, still requires some manual work.

Thus, I was wondering whether any volunteers would be willing to help building
ISO images for the various architectures. A rough guide can be found in [2]
from which the the d-i part can be omitted, however, a local mirror available
through the filesystem is still necessary (see MIRROR in CONF.sh). So, reprepro
needs to be used to set up a local mirror or the remote mirror needs to be
mounted with a FUSE module or similar.

In order to use the debian-installer images for building CD images, they have
to be downloaded and extracted (for the remaining Ports architectures above)
and placed into the directory pointed to by DI_DIR in the easy-build.sh
script, e.g.: export DI_DIR="/srv/d-i/debian-installer/installer/build/tmp/cdrom/.

Would be great if we could get several people work on this and create ISOs
for alpha, hppa, powerpc, ppc64 and so on. Please note: It's not necessary
to run debian-cd on the same architecture as the target architecture of
the ISO images. Hence, using an amd64 host should be fine.

Thanks,
Adrian
