интерфейс D-Bus системы d-logind (The D-Bus interface of systemd-logind)
Вступление (Introduction)
systemd-logind.service(8) is a system service that keeps track of
user logins and seats.
The daemon provides both a C library interface as well as a D-Bus
interface. The library interface may be used to introspect and
watch the state of user logins and seats. The bus interface
provides the same functionality but in addition may also be used
to make changes to the system state. For more information please
consult sd-login(3).
