nix infrastructure

This is my flake-parts based NixOS infrastructure repository. Hosts are declared once in parts/hosts.nix; the same inventory generates nixosConfigurations, package build aliases, and colmenaHive deployment nodes.

Layout

• parts/ contains flake-parts modules: host inventory, Colmena integration, and the dev shell.
• lib/ contains small helpers such as mkHost.
• hosts/<name>/ contains host-specific hardware, disk layout, persistence, users, and local policy.
• profiles/nixos/ contains opt-in machine profiles such as base, laptop, desktop, server, and laptop-server.
• modules/nixos/ contains reusable NixOS functionality.
• modules/home/ contains Home Manager configuration for the <user>environment.
• assets/ contains repository-owned files referenced by modules, such as wallpapers.

Hosts

• shade is my personal Lenovo X1C 6th Gen laptop. It imports base, laptop, and desktop, uses Home Manager, impermanence, Hyprland.
• dusk is a laptop-server / edge host for small services. It imports base and laptop-server, is managed by Colmena, and deploys to dusk.local as root.

Topology (WIP)

nix-topology is wired through flake-parts and receives the generated NixOS configurations. Build the diagrams with:

nix build .#topology

The output appears under result/ and contains rendered SVG topology diagrams.

Common Commands

nix develop
nix flake check --no-write-lock-file
nh os build
nh os test
nh os switch
