You don't need to save bandwidth over your LAN, do you? Does anyone know exactly what's happening during the rebuild? I understand from light documentation how deltarpm works, what I'm not sure is if most of the time is spent reconstructing a virtual oldrpm from an installed rpm, or applying the delta, or writing out the new install? If it's not the former reconstruction aspect, it seems like a Btrfs aware deltarpm could simply write out the delta blocks to disk, which would be rather small, and then obsolete the old ones if the operation is successful. Fully rewriting the files isn't necessary by design with Btrfs.
