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.
