Okay, we really ought to rename this stuff soon. Pacemaker uses the term "rhcs" to mean "standard fence agents" -- the kind that are from the ClusterLabs/fence-agents repository. Pacemaker actually decides "this agent is an RHCS-style agent" if it lives in `PCMK__FENCE_BINDIR` (which is /usr/sbin on my machine) and starts with "fence_". Sigh. Sorry to bother everyone.
