@jguiditta , good catch on o-p-m changing out from under us.  However, I think this PR is still doing the right thing given the message from from the o-p-m pull request, "Firewalld package cannot be uninstalled, because other packages might be dependent
on it. This patch makes just firewalld service to stop and be disabled."
