Specifies whether the .snapshot directory is visible on this volume at the client mount points.
To CIFS users, the snapshot directory is displayed only at the root of a share. For example, if a user's home directory is a share named Bill that corresponds to the /vol/vol0/home/bill directory, only the /vol/vol0/home/bill/.snapshot directory is visible.
When this user displays the contents of the home directory, the snapshot directory is displayed as ~snapshot if the operating system supports long file names and as ~snapsht if the operating system supports only short file names.
