• If you have images in your hauler store with a layer of type application/vnd.docker.image.rootfs.foreign.diff.tar.gzip (usually with windows arch images), the registry fails to start.

multiple errors returned: UNKNOWN: unknown error; UNKNOWN: unknown error; map[]; MANIFEST_BLOB_UNKNOWN: blob unknown to registry;

What is the new behavior (if this is a feature change)?

• registry validates the layer and starts up normally.
