It works on netbsd-7:

bacasel# mountd
bacasel# nfsd
bacasel# showmount -e         
Exports list on localhost:
/mnt/test/dir                      127.0.0.1 
/mnt/test                          127.0.0.1 
bacasel# mount -t nfs 127.0.0.1:/mnt/test /mnt2
bacasel# mount            
/dev/xbd0a on / type ffs (log, NFS exported, local)
/dev/xbd1a on /d type ffs (extattr, log, local)
kernfs on /kern type kernfs (local)
ptyfs on /dev/pts type ptyfs (local)
procfs on /proc type procfs (local)
tmpfs on /var/shm type tmpfs (local)
127.0.0.1:/mnt/test on /mnt2 type nfs
bacasel# pkill -9 mountd nfsd
bacasel# ps -ax|egrep '(nfsd|mountd)'
bacasel# umount -f /mnt2
bacasel# mount
/dev/xbd0a on / type ffs (log, NFS exported, local)
/dev/xbd1a on /d type ffs (extattr, log, local)
kernfs on /kern type kernfs (local)
ptyfs on /dev/pts type ptyfs (local)
procfs on /proc type procfs (local)
tmpfs on /var/shm type tmpfs (local)
