Pin Nixpkgs for Reproducibility

This tip is a summary of information taken from the nix.dev tutorials.

Importing <nixpkgs> may be convenient for quickly checking if you can correctly create a working Nix expression by importing Nix packages. However doing so doesn't create a fully reproducible Nix expression.

Pinning an exact version of Nixpkgs will create fully reproducible Nix expressions. This can be done like so:

{ pkgs ? import (fetchTarball "https://github.com/NixOS/nixpkgs/archive/06278c77b5d162e62df170fec307e83f1812d94b.tar.gz") {}
}:

...

It is recommended to follow the latest stable NixOS release (ex: nixos-23.11), or the latest unstable release (nixos-unstable).

However, a list of all the releases and the latest commit can be viewed at status.nixos.org.

More examples of pinning nixpkgs can be found here.
