Why is rm not a neat way? Is it because the container deployment tool needs to
know about gluster internals? But isn't a Dockerfile dealing with details
of the service(s) that is being deployment in a container.

If container deployment needs are different it should should address issues like
above. If we start addressing glusterd's configuration handling for every
new deployment technology it would quickly become unmaintainable.
