For file systems other than ZFS,
this location can be any directory and does not
need to be within an exported file system. If it is not in an exported
file system, a very limited set of operations are permitted, so that an
NFSv4 client can traverse the tree to an exported file system.
Although parts of the NFSv4 tree can be non-exported, the entire NFSv4 tree
must consist of local file systems capable of being exported via NFS.
All ZFS file systems in the subtree below the NFSv4 tree root must be
exported.
NFSv4 does not use the mount protocol and does permit clients to cross server
mount point boundaries, although not all clients are capable of crossing the
mount points.
