s6-rc

What is it ?

s6-rc is a service manager for s6-based systems, i.e. a suite of programs that can start and stop services, both long-running daemons and one-time initialization scripts, in the proper order according to a dependency tree. It ensures that long-running daemons are supervised by the s6 infrastructure, and that one-time scripts are also run in a controlled environment.
