On a somewhat related note, will the installer ever be upgraded to handle
BSD4.4 filesystems? When I got a new hard drive a few months ago I had
some trouble using mkfs on it, so I just newfs'd it. Now none of my six
partitions (on two hard drives) are usuable in the Installer. This isn't a
special concern to me since my MacOS partition is only something like 15
megs, holding a minimal system and a few NetBSD utils (like the booter).
It does affect my ability to mount the filesystems in the Installer's
minishell so I can cpout to floppy disks and such.
