Correct, and of course asking the question both ways is relevant.
I have a few questions though, is BFFS-4.4 compatible with UFS or does
NetBSD support Minix V2? In that case it might be possible to share
partitions though I definately wont recommend trying to share any kind
of system files.

Correct, Linux currently does not use the RDB partition-type for this.

Couldn't have put it better myself.

The M68060 and the CS mkI SCSI are currently supported by Linux
(latest release it 2.0.22). A beta driver for the CS mkII is available
but we do not know if it actually works as we have not been able to
test it yet, due to lack of hardware access (the changes from mkI to
mkII are pretty trivial so I think there is a pretty good chance that
it will work).

A driver for the Piccolo (and all the other Cirrus Logic based boards)
is in the works, but has not been released for beta-testing yet.
