   AFS prefers ReadOnly Volumes to ReadWrite Volumes,
   until it gets to a ReadWrite Volume.   So normally,
   the top of your afs tree is readonly and the actual
   data volume leaves are readwrite.

   So:
       touch /afs/@cell/user/matthais/file

   works fine, because:

             /afs/@cell/user/matthais/file
              RO  RO    RO   RW
   but:
       touch /afs/@cell/file
              RO  RO    uh-oh

   fails.  Thus, the dot-cell RW mountpoint, thus:

       touch /afs/.@cell/file
              RO  RW

   works.
