commit 783a44f9e98953e3359fd5ccc1788d993808fa64
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>

    Log less/better about systemd at startup
    
    Report errors if the notification fails; report success only if it
    succeeds; and if we are not notifying systemd because we aren't
    running with systemd, don't log at notice.
