## Service is running as "root":

 Since it interacts directly with systemd over D-Bus, the fleetd daemon must
 be run with elevated privileges (i.e. as root) in order to perform
 operations like starting and stopping services. From the systemd [D-Bus
 documentation](http://www.freedesktop.org/wiki/Software/systemd/dbus/):

    In contrast to most of the other services of the systemd suite PID 1
    does not use PolicyKit for controlling access to privileged operations,
    but relies exclusively on the low-level D-Bus policy language. (This is
    done in order to avoid a cyclic dependency between PolicyKit and
    systemd/PID 1.) This means that sensitive operations exposed by PID 1
    on the bus are generally not available to unprivileged processes
    directly.
