To clarify a little, in pulp-docker-2.0.0 (not released or even alpha
built yet), we are going to have a new data type called a Manifest.
Rather than interacting with and promoting layers, users will now
interact with Manifests. The Manifests themselves reference the layers
(now called Blobs). So to remove a Blob that has a security problem is
simply a matter of removing the Manifests that reference it and then
running an orphan cleanup. Pulp itself will automatically remove Blobs
from repositories as soon as all Manifests that reference them are
removed, the orphan cleanup is for removing the Blobs from Pulp entirely
when no repositories reference them.
