For variety, I also present my result of doing this using the rc(1) shell (the Byron Rakitzis implementation [1]). Boot up an Alpine Linux in a virtual machine, follow the README in the tarball, and you would be able to get a working s6/s6-rc/rc (well the name...) based system. It is admittedly designed based on Alpine, but should be to some extent portable: Alpine uses a user space based on busybox, so I think most commands should be able to run as is, since a user space based on GNU/util-linux/... would be more permissive in most aspects.
[1] <https://github.com/rakitzis/rc>. Why still using a shell has just been thoroughly explained by Laurent (I think a point to add is that using the shell for run scripts makes instanced services very easy to implement); the rationale for using rc(1) was explained in [2], which is also where I first posted my results. The current version has accumulated a lot of updates, and should be significantly better.
