A problem might be dealing with mounts cloned from the parent namespace at container creation. Ideally they wouldn't be duplicated so they wouldn't need to be cleaned up (perhaps that's justified given the requirement above). Another thought is, what would happen on just cloning a namespace, not necessarily as a container (is that even a sensible question)? The user may actually want the mounts in this case, and can we even tell the difference at namespace creation? > > But I agree that adding safeguards against cases which don't have such > easily defined semantics (such as triggers from several different > namespaces).
