This is a modular NixOS configuration using Nix flakes and home-manager in standalone mode. It manages both system-level (NixOS) and user-level (home-manager) configurations for a reproducible, declarative Linux environment.

• Flake-based: Leverages Nix flakes for reproducible builds and dependency management.
• Modular Structure: Organized into modules/ (system modules), apps/ (user applications), and packages/ (system packages) for easy maintenance.
• Custom Inputs: Includes bleeding-edge software like niri (Wayland compositor), zen-browser, and theming with catppuccin.
• Standalone Home-Manager: User configs are managed separately from NixOS for flexibility.
• Theming: Consistent catppuccin theme across system and applications.

• flake.nix: Main flake definition with inputs and outputs.
• hosts/: Per-host configurations (e.g., hosts/sol/configuration.nix).
• users/: Per-user Home Manager configurations (e.g., users/bye/home.nix).
• modules/: System-level modules (e.g., fonts, printing, virtualization, niri WM).
• apps/: User applications and tools (e.g., GUIs, CLIs, web apps).
• packages/: System modules for packages (e.g., gaming, syncthing, kanata).
• flake.lock: Locked flake dependencies.

1. Prerequisites: Ensure Nix is installed with flakes enabled (nix.settings.experimental-features = ["nix-command" "flakes"]).
2. Clone and Build:

   git clone <this-repo>
   cd nixconfig
   sudo nixos-rebuild switch --flake .#sol  # For system config
   home-manager switch --flake .#bye        # For user config

3. Update: Run nix flake update to refresh inputs, then rebuild.
4. Secrets: Sensitive data (e.g., passwords) should use agenix or sops-nix instead of hardcoding.

• Rebuild System: sudo nixos-rebuild switch --flake .#sol
• Rebuild User: home-manager switch --flake .#bye
• Check Flake: nix flake check (add this for validation).
• Modules: Enable/disable in modules/default.nix, apps/default.nix, etc.

• Add new modules in modules/ and import in modules/default.nix.
• For packages, add to packages/ subdirs and import in packages/default.nix.
• Use overlays in flake.nix for custom package modifications.
• To add a user: Create vars/newuser.nix with overrides and import in flake.nix.

• If rebuild fails, check nix.log or run journalctl -u nix-daemon.
• For home-manager issues, ensure standalone mode is set.
