интерфейс D-Bus системы systemd (The D-Bus interface of systemd)
SCOPE UNIT OBJECTS
All scope unit objects implement the
org.freedesktop.systemd1.Scope interface (described here) in
addition to the generic org.freedesktop.systemd1.Unit interface
(see above).

Methods
Abandon() may be used to place a scope unit in the "abandoned"
state. This may be used to inform the system manager that the
manager that created the scope lost interest in the scope (for
example, because it is terminating), without wanting to shut down
the scope entirely.
Signals
RequestStop is sent to the peer that is configured in the
Controller property when systemd is requested to terminate the
scope unit. A program registering a scope can use this to cleanly
shut down the processes it added to the scope instead of letting
systemd do it with the usual SIGTERM logic.
Properties
All properties correspond directly with the matching properties
of service units.
Controller contains the bus name (unique or well-known) that is
notified when the scope unit is to be shut down via a RequestStop
signal (see below). This is set when the scope is created. If not
set, the scope's processes will terminated with SIGTERM directly.
