For the record, runit's code is in really bad shape.

It uses deprecated APIs, and also hasn't been updated from K&R C. There are a number of type warnings on 64-bit systems. The build system cannot be used for cross-compilation, and compiling/installing it is a disaster kind of generally.

Runit's licensing is all over the place, and its documentation is incomplete/inaccurate. It's been abandoned by its creator, as near as I can tell. I tried to get in touch with him a couple of years ago to offer some fixes, and got radio silence. There is no apparent way to contribute code to the project.

I've never used the busybox version, and so I can't speak to that one. But upstream runit has been a dead project for years, and badly needs to be forked by the distros that use it.
