@ericonr I will write an INSTALL.msg ;)
@ahesford Ι fully agree with getting -F out of $OPTS. I am using the same logic in the [66 services](https://github.com/mobinmob/void-66-services).  I think there are others runit services in the repo that can benefit from something similar - that is seperation of optional and mandatory switches.  Key generation is a part of all three ssh services in the repo (openssh, dropbear, tinyssh).
@Vaelatern It is ultimately a matter or policy. Disabling password login for root is a good practice. Users can rely on all sorts of things :)
