We discovered this is:
https://bugzilla.redhat.com/show_bug.cgi?id=1328961

However...while I see the value in RegisterMachine for "fat" and long-running containers
that run systemd recursively, I'm not sure I see what we're gaining in e.g.
a Kubernetes/OpenShift microservice environment.

We already have a daemon-talking-to-a-daemon issue, RegisterMachine
adds another daemon into the chain.

Relatedly, do we really need *both* oci-systemd-hook and oci-register-machine?

If we folded them together, we could use this bit:

	if (strcmp("init", cmd_file_name) && strcmp("systemd", cmd_file_name)) {
		pr_pdebug("Skipping as container command is %s, not init or systemd\n", cmd);
		return EXIT_SUCCESS;
	}

to also skip calling RegisterMachine?
