It can if the journal is clean (eg Mac OS X safely unmounted it at
shutdown) and you use the "force" option. That should be OK for a
data partition, but I'm not sure I would want to do that for the
Mac OS X root partition.

I haven't used Snow Leopard, so can't answer that. But another problem
with UFS is being dependent on Apple continuing to support it in
future Mac OS X releases.


So you are kind of stuck with what the propriety OS can support and
what the open source OS can reverse-engineer from the propriety OS.

If HFS+ and UFS don't work then FAT32 may be your only option for
something that both OS know well. I would recommend keeping a backup
of whatever you put on FAT32 for when the inevitability fuckup happens.
