<para>The service manager exposes a number of objects on the bus: one

for each unit and for each queued job. The unit objects each implement a generic
for each unit and for each queued job. The unit objects implement a generic
<interfacename>Unit</interfacename> interface as well as a type-specific interface. For example, service units
implement both <interfacename>org.freedesktop.systemd1.Unit</interfacename> and
<interfacename>org.freedesktop.system1.Service</interfacename>. The manager object can list
unit and job objects or directly convert a unit name or job id into a bus path of the corresponding
unit and job objects or directly convert a unit name or job identifier to a bus path of the corresponding
D-Bus object.</para>

<para>In contrast to most of the other services of the systemd suite, PID 1 does not use
<ulink url="https://www.freedesktop.org/software/polkit/docs/latest/">polkit</ulink>
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 polkit and systemd/PID 1.) This
means that sensitive operations exposed by PID 1 on the bus are generally not available to unprivileged
processes directly. However, some operations (such as shutdown/reboot/suspend) are made available through the D-Bus
API of logind, see
