# 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.
