rhc is a commandline tool which uses the D-Bus API to connect
to the rhsm service. When a system is being registered or unregistered,
virt-who must be notified about that. For that, rhsmcertd needs
to read /run/virt-who.pid, and if the service is running, it sends
to virt-who the SIGHUP signal so that virt-who is restarted.
