Comment 7 for bug 1434722

IMHO if we're unlucky and in full rsync mode there's no way to know if there are changes or not in this particular case, having BIT create a new snapshot every time even if it might be equal to the previous one when full rsync mode is enabled, is a compromise that is far better than having a "wrong" snapshot or suppress the full rsync mode at all.
On the contrary, as I said earlier I would prefer to have a snapshot preserved in any case, independently from this problem.
