[Nix-dev] How to build all of nixpkgs?

[Tomasz Czyż]

Look there, that's how all packages are build by CI:
http://hydra.nixos.org/jobset/nixpkgs/trunk#tabs-configuration
It uses pkgs/top-level/release.nix to build all of that.
Also it passes nixpkgs. So maybe you need to do something like

nix-build -I nixpkgs=path-to-your-nixpkgs pkgs/top-level/release.nix (and
eventually pass other options like officialRelease etc)
