Wrong assumption.

In fact, support for shipping ocf:pacemaker:controld has been
explicitly restricted to cases when CMAN logic (specifically the
respective handle-all initscript that is in turn, in that limited use
case, triggered from pacemaker's proper one and, moreover, takes
care of dlm_controld management on its own so any subsequent attempts
to do the same would be ineffective) is _not_ around:

(accidental syntactical typos were fixed later on:

To recap what others have suggested:
