Description Vladimir B. Grebenschikov 2001-05-23 11:30:01 UTC 
  While working with unionfs:
  If a directory is found in the lower layer, and there is no entry in the
  upper layer, then a shadow directory will be created in the upperlayer.
  It will be owned by the user who originally did the union mount, with
  mode `rwxrwxrwx'' (0777) modified by the umask in effect at that time.
  So inbasic unionfs policy do all think like user copy directory structure
  by his own hand.

  I want possibility to give user exactly same stucture as on below layer,
  with same uid/gid/mode as on lowerlayer.

  Patch attached provide possibility use -a key to /sbin/mount_union.

  In case of the -a option the newly mirrored upper-layer directory will
  have the same attributes as the lower-layer directory.

  And same thing with files.
