Thanks.  I finally had the chance to do that.  But it still doesn't 
work.  Could the following error messages be a clue? 

hendrik@lovesong:~/dv/lang/frith$ mtn commit
lockd: cannot monitor 172.25.1.11
lockd: failed to monitor 172.25.1.11
mtn: error: sqlite error: database is locked
hendrik@lovesong:~/dv/lang/frith$

I also occasionally get similar messages from fam

The /etc/fstab entry for /farhome is

172.25.1.11:/farhome  /farhome nfs noauto,user,defaults,rw,hard,tcp,lock,vers=3,exec,nodev 1 1

And the /etc/exports entry on 172.25.1.11 is

/farhome         172.25.1.2(rw,sync,no_root_squash,map_identity) 172.25.1.3(rw,sync,no_root_squash,map_identity) 172.25.1.4(rw,sync,no_root_squash,map_identity) 172.25.1.9(rw,sync,no_root_squash,map_identity) 172.25.1.12(rw,sync,no_root_squash,map_identity) 172.25.1.32(rw,sync,no_root_squash,map_identity) 172.25.1.33(rw,sync,no_root_squash,map_identity) 172.25.1.6(rw,sync,no_root_squash,map_identity) 172.25.1.8(rw,sync,no_root_squash,map_identity) 172.25.1.9(rw,sync,no_root_squash,map_identity)

The machine I ran the mtn commit from was 172.25.1.4 (the third entry on 
the above list)

I always enjoy reading your posts on debian-user, by the way.  Somehow a 
sunny personality manages to shine through the dry tech stuff.
