Comment 12 for bug 451613

On 12.10, the live session also mounts all my harddisk partitions. (disk icons show up on the unity left panel) As the ext4 partitions are still mounted in a hibernated session, the mounting caused file system error after resuming and failed to boot. (recover mode fails too) I would suggest that this kind of behavior in live session should be done in read only mode if it's really needed. Same for hibernated windows partitions.
