Try

	% mount -r /dev/rz4c /mnt

The -r stands for "read-only."  That's what the "restricted operation" complaint
is about.

The file system type "cdfs" is for ISO 9660 format CDs.  The distribution CD is in
UNIFILE format.  That's what the "unknown descriptor type" message is complaining
about.

Hope this clears things up.
