Here's how to use Home Manager without home-manager. @proofconstruction is my witness.

Getting the right version of Home Manager

First of all we have to make sure that the version of Home Manager matches the Nixpkgs release we want to use for our user environment configuration. Otherwise we will almost certainly get into trouble with mismatching interfaces.

We start out with a function that takes Nixpkgs as pkgs and fetch the appropriate Home Manager release. We get the given Nixpkgs version string from pkgs.lib.version and split it into the . format with lib.versions.majorMinor.
