Issue Description

When transferring an image to and from rootful containers-storage, the manifest type changes from OCI to Docker, which causes some tools (i.e. Bootc) to break.

This also causes the digests to differ.

Steps to reproduce the issue

Describe the results you received

Transferring an image with an OCI manifest to rootful storage changes to a docker manifest.

Describe the results you expected

The manifest type should remain the same. Or alternatively this limitation should be documented in the docs.
