Joerg already tried to combine i386/ppc/amd64/hppa and
i386/ppc/amd64/sparc.

the later one always made the medium unbootable.

Would be a nice task, as we would know then, which Arches are
combinable.

Try asking the quation at debian-cd@xxxxxxxxxxxxxxxx . It would be great if you post the results of your findings to this list, but it seems noone here has good ideas for solving those problems...

Joerg already tried to combine i386/ppc/amd64/hppa and i386/ppc/amd64/sparc. the later one always made the medium unbootable. I'm really curious how this was done, especially the first combination. Perhaps if everyone could see the scripts that Joerg currently has, then we could all use that as a study material for the debian-cd rewrite and as examples of tricks to try making other architectures bootable on the same CD? -- Martin-Eric Racine http://q-funk.iki.fi
