Hmm, that is weird. When I use mount -v it actually does mount the
remote NFS tree. Here is the output:

root@...om:~# mount -v lemmy:/data/repos /data/lemmy/
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Thu Jun  7 17:21:54 2012
mount.nfs: text-based options: 'addr=165.204.15.93'
mount.nfs: mount(2): Protocol not supported
mount.nfs: trying 165.204.15.93 prog 100003 vers 3 prot UDP port 2049
mount.nfs: trying 165.204.15.93 prog 100005 vers 3 prot UDP port 39332
mount.nfs: text-based options (retry): 'addr=165.204.15.93,vers=3,proto=udp,mountvers=3,mountproto=udp,mountport=39332'
lemmy:/data/repos on /data/lemmy type nfs (rw)

When I unmount and try to mount it again without -v I still get the
error message and the mount fails.

With 3.4 the mount -v output is:

mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Thu Jun  7 17:19:44 2012
mount.nfs: text-based options: 'addr=165.204.15.93'
lemmy:/data/repos/ on /data/lemmy type nfs (rw)

So for some reason the text-based options are different. Maybe that has
something to do with the problem.

Regards,
