> I can expand on this more with a comment directly from the customer requesting this: > > * rsync is useful in the docker-registry container for migrating docker-registry's /registry/ folder from the default NFS to GlusterFS when performing migrations. Registry is owned by Devexp and I'm going to move this bug to them. > Only core images that need rsync are impacted. > What images are these? Can Engineering provide a list? These are all the images mentioned in OCP Container Images table, but each is owned by a different team that should properly update their Dockerfiles. > Why exactly don't we want to include one package in a base image? We want to keep base image as the smallest possible unit that contains ONLY the necessary common tooling for images. If you want support rsyncing into images (we rarely do in our images, registry being one exception for now) we don't include it.

Description of problem: In 3.10, the ose-base image no longer installs git, which included rsync as a dependency. This means that rsync is no longer installed in almost Any container that uses the ose-base image (for example the docker-registry) during creation. This means that `oc rsync` no longer appropriately uses rsync in the container and instead defaults to remote tar, assuming tar is available in the container.
