With the interface I understand what you mean. But if you look at things like alpine-conf these are wrapper script for alpine linux specifically. It wouldn't be fair to compare it with a tool that targets portability. We could add rc-service like commands very easily.
Even if s6-rc doesn't have native event handling it should be easy to create an event handler service that starts/stops services on events. (to be tested)
@sertonix sure, alpine could build its own frontend to s6-rc.
but then alpine will have to also build suitable replacement polyfills for everything else that is presently buggy.
or alpine could use systemd and allocate resources to other projects.
