multiarch debian-installer

[Goswin von Brederlow <brederlo@informatik.uni-tuebingen.de>]

Hi,

since amd64 and em64t cpus are capable of running both 32bit and 64bit
it would be nice to have a multiarch debian-installer that lets the
user choose which one to use. I know amd64 will not be part of sarge
but hear me out please.

My idea is to add kernel-image-di-amd64 udebs to i386 and to add one
more question '[ ] 32 bit | [ ] 64 bit' to D-I which is conditional on
the booted kernel (only ask with a 64bit kernel) and passes "-aamd64"
to debootstrap for 64bit. The D-I would still run 32bit but would
install 64bit into target. Afaik nothing more is needed.

Debian-cd can then add another kernel image to the CD and provide a
linux-2.6-64 option at the boot prompt for people willing to
experiment.


What do you think?

MfG
