This is a patch by Maxim Suhanov <suhanov/group-ib.ru> aiming to provide integrity and authenticity check for stage2 rootfs image when required: - media bootloader passes sha256 hash of stage2 image; - stage1 early userspace code (that is, propagator) checks the candidate files against that during search; - existing file with different checksum results in a warning with a dialog to just say NO, continue searching for the proper squashfs image and have a look at that weird one; - existing file with correct checksum results in booting as usual. The check is triggered by "hash=..." kernel boot parameter. See also http://www.forensicswiki.org/wiki/Forensic_Live_CD_issues
