On Fedora 19, there is a delay between the time loop0p2 is created to the time it is ready to be mounted. This patches waits for 5 seconds for /dev/mapper/loop0p2 to be accessible. If it is not ready then the script exits with status 1. Fixes: bug #1197340 Change-Id: Iff0cfd0566673799a77500e0e24954f5f3743a17
