4	  An overlay filesystem combines two filesystems - an 'upper' filesystem
5	  and a 'lower' filesystem.  When a name exists in both filesystems, the
6	  object in the 'upper' filesystem is visible while the object in the
7	  'lower' filesystem is either hidden or, in the case of directories,
8	  merged with the 'upper' object.
