      Something is going wrong here in our retry loop.   I think it might be that we don't clear the pending deployment on failure.  IOW we need to

      rpm-ostree cleanup -p

      before we rertry.

       

      This is fallout from https://github.com/openshift/machine-config-operator/pull/3580 - Although I suspect it may have been an issue before too.
