> I don't know how to properly fix this other than to have a ./finish script clean up any lingering saned processes, but I’m not sure how safe that is. If there is no acceptable solution I can drop the runit service from this PR.

I think documenting this limitation in the commit and maybe the service file itself is necessary, as a start. Not sure how to go about actually fixing it... Have you considered opening an issue upstream?
