Comment 9 for bug 573919

I also have this problem under Ubuntu 10.04LTS.
Running the automounter manually (thanks onkara), on attempting to change to an NFS-mounted directory, I noticed:

>> mount.nfs: rpc.statd is not running but is required for remote locking.
>> mount.nfs: Either use '-o nolock' to keep locks local, or start statd.

On starting statd ("sudo start statd") and autofs ("sudo start autofs"), the automounter is now working.

Neither autofs nor statd appear to be in /etc/rc?.d/
