I remember doing this a couple of years ago. I think this can be compared to bootstrapping a compiler toolchain on a new target. The point being that the nix that you built is only half way. It will “live” in /nix/store but know how to build for /foo. You will need to build a third nix using that second nix that will live in /foo and build for /foo. Knedlsepp in discourse.nixos
