NFSv4 mounts are relative to the filesystem being exported.  NFSv3
mounts are absolute paths on the server.

IOW, if you export /pool/backup/sites/m/ on the server, then the mount
line on the client is just:
  mount -o vers=4 server4:/ /mnt

If you export / on the server, then the mount line on the client would be:
  mount -o vers=4 server4:/pool/backup/sites/m/ /mnt

This tripped me up when I tried converting my NFSv3 setup at home to NFSv4.
