I have had unexpected problems in mounting my `netbsd:/cdrom' directory
to a Solaris and Digital UNIX (alpha) system. After a lot of trial and
error I found out, with the help of colleages, that the problem was
caused by the fact that NFSD on NetBSD uses by default the UDP and
*not* the TCP protocol. So the problem can be easily solved by starting
the NFSD daemon with the `-ut' flags. For example with next lines in
/etc/rc.local:

------------- part of /etc/rc.local -----------------------------
# start NFS and MOUNT daemon
if [ -f /etc/exports ]; then
        echo 'Starting NFS and MOUNT daemon'
        /sbin/nfsd -ut          # -t necessary for TCP protocol !!!
        /sbin/mountd
fi
------------- part of /etc/rc.local -----------------------------

Perhaps this `nitty-gritty-detail' can be added to the *BSD FAQ?
