Also, overlayfs is really recently added to the kernel. It's much much newer than device mapper stuff. So I wouldn't call it immature. You might be thinking of the thin provisioning snapshots which is much newer, but still has been around longer than overlayfs. But I don't think the live media is using thin snapshots (?) I think they're the conventional (thick) type.

However I don't see the same snapshot message in that bug, that you get.
