Unrelated to suckless, there's a project (confusingly) named stal/IX: https://stal-ix.github.io/

It is also a statically linked Linux distribution. But it's core idea is reproducible nix-style builds (including installing as many different versions/build configurations of any package), but with less pl fuff (no fancy funcional language - just some ugly jinja2/shell style build descriptions; which in practice work amazingly well, because underlying package/dependency model is very solid - https://stal-ix.github.io/IX.html).

It is very opionated (just see this - https://stal-ix.github.io/STALIX.html), and a bit rough, but I was able to run it in VMs sucessfully. It would be amazing if it stabilizes one day.
