nfs installs of 5.1

[M. L. Dodson]

Background:
I posted this on questions, but got no response.  Since this used
to work, I thought it might be a 5.x issue.

$subject seems broken for me for 5.1 miniinst.iso

Export /cdrom from 10.2.1.4; exports line:
/cdrom -maproot=0 -alldirs -network 10.2 -mask 255.255.0.0

Nfs server setup, on 4.8-STABLE, is well tested and known to
work.

When prompted for nfs info during install, give 10.2.1.4:/cdrom,
netmask 255.255.0.0 (same subnet as target machine) -> configure
install target network (ip 10.2.1.200) -> get error:

Error mounting 10.2.1.4:/cdrom on /dist: no such file or directory

On ttyv4 find error messages (hand copied):
mount_nfs: can't update /var/db/mountdtab for 10.2.1.4:/cdrom
mount_nfs: Operation not supported by device

On ttyv4 I can cd to /dist

Anyone have suggestions?

TIA,
Bud Dodson
