   UnionFS is a stackable unification file system, which can appear to
   merge the contents of several directories (branches), while keeping
   their physical content separate. 

   Unionfs is useful for unified source tree management, merged contents
   of split CD-ROM, merged separate software package directories, data
   grids, and more. Unionfs allows any mix of read-only and read-write
   branches, as well as insertion and deletion of branches anywhere in
   the fan-out.
