Статус выхода (Exit)
On success, 0 is returned. If systemd-run failed to start the
service, a non-zero return value will be returned. If systemd-run
waits for the service to terminate, the return value will be
propagated from the service. 0 will be returned on success,
including all the cases where systemd considers a service to have
exited cleanly, see the discussion of SuccessExitStatus= in
systemd.service(5).
