[Review] Request from 'schubi2' @ 'yast/yast-autoinstallation/review_140825_second_stage'

Please review the following changes:
  * 0bd3a7a packaging
  * 034a32a making second_stage public in order to switch off completely
  * 7063df8 imaging: check for script entry only

this looks strange. It looks like you switch from image in location to force script usage for image usage.
