 * `service_cgroup_cleanup = no` — Kill the entire cgroup on watchdog cleanup. Note that it is distinctly not the same as killing the cgroup on stopping.
 * `service_success_exit = 0` — Array. Which exit codes to treat as successful termination. Only works for managed services (With no custom pidfile).
 * `service_oneshot = no` — The service is supposed to do something and die instead of daemonizing.
+* `service_signals_passthru` — Array, empty by default. Which signals should the svc pass directly to the service mainpid. This is dangerous, use with caution.
