🏗️ Project Architecture

Flake Structure (flake.nix)

This repository uses a unified multi-host flake architecture.

• Inputs: Defined in flake.nix (nixpkgs, home-manager, stylix, agenix, etc.).
• Outputs: Generates nixosConfigurations for all hosts.
• makeNixosSystem: A helper function in flake.nix that standardizes host creation:
  • Injects specialArgs: host, username, sharedVariables, hardwareProfiles.
  • Sets up Overlays: Custom packages and fixes.
  • Configures Home Manager: Integrated directly into the NixOS system.
