There is no change to a pull where --storage is ostree. But for docker, we now use skopeo copy to "pull" and image from a registry and verify its signature (should the policy require it). When docker is the destination for skopeo copy, it requires a tag. If no tag is given by the user, we inject "latest". Closes: #586 Approved by: baude
