It is the simplest layered file system. The overlay interposes itself 
between the underlying fs and new access.

Since the overlay just passes commands along, it does not change behavior. 
Except that you could probably have a read-only overlay on top of a 
read-write file system and NFS export the read-only overlay.

It is mainly intended to serve as a prototype for new layered file 

Take care,
