the original nix files remained mostly broken and unmaintained - what's makes this time around different? does anyone else use nix really?

I've switched to NixOS on a new computer and I'll be using this on a daily basis. It's also something that I could see us using in the CI down the road (it's a way to pin down all software that is being used during the build - e.g. compilers, system libraries, etc).

if anything we should be using the same docker images we use for creating binaries so we test with the same gcc/glibc/patches
