Nix Configuration

This repository contains my personal Nix flake used to manage both NixOS and macOS systems. It also defines collections of Home‑Manager modules and a few custom packages.

The flake makes heavy use of flake-parts to break the configuration into smaller pieces. Hosts and homes are constructed using helper functions under parts/lib.

Directory layout

• hosts/ – Host specific NixOS or Darwin configurations
• homes/ – Home‑Manager setups for each user and host
• configs/ – Reusable modules shared by hosts and homes
• _nixOSModules/ – Standalone NixOS modules exported by the flake
• _homeModules/ – Standalone Home Manager modules exported by the flake
• pkgs/ – Custom package definitions
• parts/ – flake-parts modules and helper libraries

Requirements

• Nix with flakes enabled
• Optional: agenix for secrets

Building a host

# NixOS
nix build .#nixosConfigurations.<host>.config.system.build.toplevel

# macOS (nix-darwin)
nix build .#darwinConfigurations.<host>.system

Replace <host> with one of the directories under hosts/.

The resulting build can be switched to with sudo nixos-rebuild switch --flake .#<host> on Linux or darwin-rebuild switch --flake .#<host> on macOS.

If you need ssh keys for the system on darwin systems you can use the command sudo ssh-keygen -A.

Home Manager only

Home Manager configurations are located under homes/. Each host imports one of these collections. To use a home setup standalone you can build:

nix build .#homeManagerModules.<module>

Secrets

Some configurations expect encrypted secrets from my private nix-secrets repository managed with agenix. If you do not have access to that repo, you can remove the secrets.nix imports from the corresponding host/home.

Custom packages

A few small packages are provided under pkgs/. They can be built via nix build .#<package>.

This flake is a work in progress and may change frequently. Feel free to explore the modules and reuse anything that looks helpful!
