  Still, big old documents have all the information you need, and more:
the first lines of would
answer your question.

  s6 is a process supervisor. It manages daemons.
  s6-rc is a service manager. It manages the global state of a machine:
what service is up, what service is down, with dependencies between
services, and "services" being implemented by either a daemon or a
one-shot script.

  s6-rc is a management layer running *on top of* s6. It uses the s6
infrastructure to do its job, but this job is not the same at all.
