# runit - service dependencies

runit's service supervision resolves dependencies for service daemons designed to be run by a supervisor process automatically. The service daemon (or the corresponding `run` scripts) should behave as follows:

- before providing the service, check if all services it depends on are available. If not, exit with an error, the supervisor will then try again.
- write all logs through runit's logging facility. The runsv program takes care that all logs for the service are written safely to disk. Therefore there's no need to depend on a system logging service.
- optionally when the service is told to become down, take down other services that depend on this one after disabling the service.

If you want to run service daemons that do not support service supervision as described above, please refer to this page about service dependencies I wrote some time ago.
