When I built A/UX 2.0 (from the CDROM distribution) there were two
bizarre features to the installed result that concern fiilesystems:

(a) like Andrew Schnable above, I found the device /dev/dsk/cnd0s3
corresponding to the "Unreserved 1" partition I had made was missing.
But in my case, it was /dev/dsk/c4d0s3, which was in fact the ONLY
value of _n_ for which /dev/dsk/cnd0s3 wasn't there. It looks as if
the install somehow systematically fails to create this device if the
corresponding partition actually exists....on the other hand, my
"Unreserved 2" partition on /dev/dsk/c4d0s4 did have the corresponding
device created.
(b) Although I put both my root and /usr partitions (in fact, all my
A/UX partitions) on the disk at SCSI ID 4, for some reason the install
resulted in an entry in /etc/fstab for the partition with "/" as
/dev/dsk/c0d0s0, not c4d0s0. On the other hand, it managed to mount
the right thing.

I've done the install twice now from scratch (trying to fix other
problems). Both these things happened both times.
