In reply to @matthewcroughan:defenestrate.it
netrc_file is always "" because nixPath is always [] in pure-eval

Thanks for the feedback. The Nix flake variant indeed was missing in my PR. I added a few paragraphs how to add env vars to the nix-daemon (i think this is the only working way for flakes). Could you take a look again?

btw, thanks for your awesome talks on Nix for Docker (the main reason my company is willing to try Nix) and for Riscv.

Does it need to be that strict in fixed output derivations? Private git repos work too.

Any poetry2nix overrides are applied on top of nixpkgs overrides

Here's a minimal flake.nix to reproduce it
``nix
{
description = "A minimal Python project with apsw dependency";

inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
flake-utils.url = "github:numtide/flake-utils";
poetry2nix.url = "github:nix-community/poetry2nix";
};

outputs = { self, nixpkgs, flake-utils, poetry2nix }:
flake-utils.lib.eachDefaultSystem (system:
let
pkgs = import nixpkgs { inherit system; overlays = [ poetry2nix.overlays.default ]; };
in
{
packages.default = pkgs.poetry2nix.mkPoetryApplication {
projectDir = ./.;
preferWheels = false;
};

    devShell = pkgs.mkShell {
      buildInputs = with pkgs; [
        poetry
        (pkgs.poetry2nix.mkPoetryEnv {
          projectDir = ./.;
          preferWheels = false;
          overrides = pkgs.poetry2nix.defaultPoetryOverrides.extend
            (self: super: {

              (
