- Fixed misleading error message in setupReadWrite (bnc #867174)
  The function uses 'mount' to test if the read-write location
  can be mounted. If not or RELOAD_IMAGE is set the read-write part
  is created from scratch and that action is logged accordingly.
  The possible error message from the mount call is a false positive
  information here and just makes people nervous :) Thus should
  not be logged
