nix-config

This repository holds my NixOS configuration. It is fully reproducible, flakes based, and position-independent, meaning there is no moving around of configuration.nix.

Deployment is done using deploy-rs, see usage.

For the configurations' entry points see the individual hosts, as well as flake.nix. For adding overlays see overlays.

Hostnames are picked from my hostname list

Usage

Deploying

NixOS

To deploy all hosts:

$ deploy

To deploy a specific host:

$ deploy .#myHost

Darwin

For macOS hosts using nix-darwin:

$ darwin-rebuild --flake ~/src/nix-config#poincare switch

Home Manager

For non-NixOS hosts (i.e. home-manager-only systems such as beme-glaptop):

$ home-manager --flake ~/src/nix-config#myHost switch

Adding overlays

Overlays should be added as individual nix files to ./nix/overlays with format

final: prev: {
    hello = (prev.hello.overrideAttrs (oldAttrs: { doCheck = false; }));
}

For more examples see ./nix/overlays.
