The ability to mount two file systems at the same mount point.  You mount
a r/w filesystem on top of a r/o file system.  If you write to a file, it
is redirected to the r/w filesystem.  Reads come out of the r/o filesystem
unless a file of the same name exists on the r/w filesystem.

So, you could mount a r/w disk on top of a r/o dcss.  Way cool.
