When I try and use the mount command from the NetBSD-1.1 I get
the following message:

mount /dev/rz1g /tmp

mount: cannot exec /usr/sbin/mount_ffs for /tmp no such file or directory

Why is mount looking for anything in /usr/sbin???

If I try and do:

sbin/mount_ffs (or _ufs) the message I get is

Operation not supported for this device.

rz1 is an internal rz25 disk and can be mounted with the mount
command in one of the old miniroots.

Without a working mount command getting the new release installed is a
real problem.
