Description of problem: 'systemctl reload smb.service' end with error message: Failed to issue method call: Job type reload is not applicable for unit smb.service. This is evidently systemd fault; all smbd versions are able reload configuration at SIGHUP signal. Version-Release number of selected component (if applicable): systemd-44-17.fc17.i686 systemd-37-25.fc16.i686
I've fixed it upstream and created a bug for it.
