We netbooted the installer, which is one of the reasons that I think SILO to
be the culprit.

I tried live-helper for sparc from and amd64 machine and this did not work.
With your hint I tried debootstrap directly. The first stage is fine, the
second though expects to be executed in the chroot which does not work.
But isn't there something out there that I could possibly use rightaway?

Hm. I'll try.

Ah, ok. But this was always sun.

No, we have not. There is no solaris on the box any more, and at least
http://sunsolve.sun.com/search/document.do?assetkey=1-21-111292-14-1 seems to
require it.
Is there anybody who could help with some sort of a rescue disk for sparc that
we could net boot?
Many thanks
