WIP: Use Niv to pin nixpkgs releases (!165) · Merge requests · simple-nixos-mailserver / nixos-mailserver

lewo requested to merge lewo/niv into master Apr 11, 2020

Before using Niv, we were following channels meaning we can not reproduce CI jobs easily.

In this change, we use Niv to pin these dependencies. We are also addding a tests/default.nix to be able to run these tests locally.

For instance, to run the test extern.nix on the nixpkgs-19.09 release:

nix-build tests/default.nix -A extern.nixpkgs_19_09
