That's a pity, indeed.

Ah, too bad. But I guess he was primarily interested in x86 Macs.

Yes, it does. But as far as I know, 64-bit PowerMacs aren't any different
than 32-bit PowerMacs when it comes to the firmware as long as the 32-bit
Macs are using NewWorld ROMs.

What about a funding? I would actually be willing to shell out some money
for that if someone worked on implementing HFS support.

That's understandable. However, genisoimage comes from cdrkit which Debian
wants to get rid of as it's unmaintained upstream. xorriso is the tool of
choice these days and if we could use it for all targets, that would be
very much desirable.
