netbooting is the correct way on those, and the only tested way.

They should, but there seems to be some issue that need investigating. I fixed
something (missing icon) recently, so the daily builds and beta2 should be
better than sarge.

Yep, but since partman-prep and yaboot-installer is broken on those. Nobody

the problem was first observed.

partman is one of the most ugly and spaguetti-like code to play with, i wish
you luck with it.
