MacOSX supports UFS HFS and HFS+.  nothing else.

its probably better since the BSDs use UFS anyway.

i would doubt it...

i would make /home ext2 and mount that under netbsd, thier ext2
support should be good.

this has been something i have yet to get around to doing...  i was
going to look at this but OpenBSD barfed when it saw this scsi card in
my blue g3.

can someone send me more info on exactly how the netbsd bootstrap
partition is setup?

do they still require that the disk use msdos partition tables?  

it would be quite easy for me to add a netbsd= option to the ybin boot
menu, i just need more info on what file i need to execute.
