Using NFS for any file system app like Subversion or CVS is
dangerous. NFS clients typically cache file changes locally, that can
cause weird errors (file size mismatches), the rename system call may not
be atomic with NFS. If you are going to use a NAS array you are
better off setting up iSCSI access rather than NFS.
