Pass. I know (almost) nothing about HFS and HFS+. I believe that we
need the disc to be an HFS/ISO9660 hybrid for powermacs to boot
it. Yes?

UDF, not UFS. But I don't think we have tools that will do that
properly yet.
Maybe the answer is to fiddle with the HFS bits so we only have the
boot / install stuff visible in the HFS volume descriptor and leave
the rest of the files on the disc only visible through
ISO9660/RockRidge. That way the install kernel and a running system
will be able to see the packages on the disc just fine, but the host
Mac system won't. I'm playing with that now to see if it will create
an image, at least.
