After install successfully completed, should not give failed information, the screen shot, please see attachment.
Since we're doing lazy unmounts now (MNT_DETACH in loader/undomounts.c:undoMount), we cannot guarantee that /mnt/runtime will be unmounted when we call undoLoop on /dev/loop0. That's the device backing that mount point. However, we should still try because we may want to tear down other loopback devices as well. Therefore, I think the "fix" here is to just not display an error message.
