nixos config #

Hello to all, this is my NixOS config!

This configuration follows the dendritic pattern using flake-parts. Every file in modules/ is a flake-parts module that is automatically imported (no manual import lists anywhere).

Structure #

.
├── flake.nix       <-- entry point, auto-imports everything in modules/
├── flake.lock
├── assets/         <-- fonts, wallpapers, keyboard layouts, etc.
├── machine/        <-- machine-specific configuration and home tweaks
│   ├── hp/         <-- the coolest server of all time
│   ├── est/        <-- gaming PC
│   └── fw13/       <-- Framework 13 laptop
└── modules/        <-- everything lives here, flat and auto-imported
    ├── configurations.nix  <-- declares nixosConfigurations
    ├── flake-parts.nix     <-- enables flake.modules option
    ├── nixos.nix           <-- NixOS base config
    ├── roles/              <-- feature bundles composed from named modules
    └── *.nix               <-- individual feature modules

Philosophy #

Every .nix file in modules/ is a flake-parts module. Inside that directory there are "feature files", they declare flake.modules.homeManager.X or flake.modules.nixos.X named modules. Then, there are "roles", they compose named modules together. Then, machines in configurations.nix import those roles and named modules directly (inclusion is the enable mechanism, there are no mkEnableOption flags).

Usage #

Check that everything still works:

nix eval .#nixosConfigurations.$(hostname).config.system.build.toplevel.drvPath

Build without switching:

rebuild build

Switch to new configuration:

rebuld switch

Update inputs:

nix flake update
