Actually the mountpoint really doesn't have to exist at all if you are
working strictly with the pvfs2-* utilities and MPI-IO codes.  

The following steps would suffice:
$ vi /home/user/pvfs2tab
 (add these contents)
 tcp://testhost:3334/pvfs2-fs /pvfs2-anything pvfs2 default,noauto 0 0
$ export PVFS2TAB_FILE=/home/user/pvfs2tab
$ pvfs2-ls -l /pvfs2-anything

It's often the case that the "mountpoint" field is the real pvfs2
mount point, and a real directory, but that's just to limit confusion.
Which I suppose we still need to work on :>
