+If "\-null" is given as the map it is used to tell automount(8) to ignore a subsequent
+master map entry with the given path.

+It can only be used for paths that appear in the master map (or in direct mount maps).

+An indirect mount map top level mount point path can be nulled. If so no mounts from

+Direct mount map path entries can be nulled. Since they must be present at startup

+A nulled master map entry path will ignore a single subsequent matching entry. Any
