I'm not sure if avoiding Home Manager is the right choice for everyone, but it worked well for me. Home Manager isn't necessary for declarative management of the user environment -- Nix flakes can do this, too. A long time ago, I kept a single `flake.nix` in my home directory describing the packages that each of my machines needed, and ran `nix profile install .#packages.<machine>` to install them into my user profile. By doing things this way, I learned a lot about writing flakes, and this transferred to other places I used Nix. What this doesn't do that Home Manager does is dotfile management, but that's actually why I avoided HM originally. First, HM's approach is a bit clunky for my taste: each change to the configuration must be followed by running `home-manager switch` for the changes to take effect. I found this to slow down the edit-and-test loop when making changes to my shell config, etc. Second, the idea of doing all configuration in the same Nix language is cool, but most of the documentation found online about configuring, etc., `git`, will refer to the tool's usual method of configuration. So instead, I made a quick Python script that manages package installation with Nix, and dotfile management with GNU Stow. The dotfiles and Nix configuration all go into the same git repository in my home directory, so they are tracked together. I've been using this approach to manage several machines for a few years now, and it's been more than sufficient for my needs. |
