Add bootfs.snapshot and bootfs.rollback kernel parameters Unlike other filesystems, snapshots and rollbacks of bootfs need to be done from a rescue environment. This patch makes it possible to snap- shot or rollback the bootfs simply by specifying bootfs.snapshot or bootfs.rollback on the kernel command line. The operation will be performed by dracut just before bootfs is mounted.
