> I've updated to mountall 2.42ubuntu0.4 and nfs-common 1:1.2.6-3ubuntu2 -- rebooting

I would not expect mountall 2.42ubuntu0.4 to make any difference. On IRC, what I suggested was that you try nfs-common from quantal (1:1.2.6-3ubuntu2), and if that didn't work, try adding mountall from saucy (2.51). There are a number of NFS-related fixes in the saucy mountall, and these symptoms could certainly be related to one of them - particularly the mount point not being correctly tagged "remote".

Could you test with mountall 2.51?
