By default, root is treated as user -2 on the remote machine, so it
probably has very little capability.  This is set up in the file
/etc/exports on the remote machine; it is called `root squashing'.
Add the option `no_root_squash' to the appropriate line in /etc/exports.

`man exports' for details.
