Bernardo Magri 528447cc19 feat: smarter installer + Nomarchy os-release rebrand
Hardware:
- New installer/hardware-db.sh: flat regex table mapping sys_vendor +
  product_name to nixos-hardware modules (Framework, Dell, Lenovo, Surface,
  ASUS, Apple T2, System76).
- install.sh:select_hardware now auto-detects CPU vendor, GPU vendor, chassis
  type, and known model, then offers Accept / Add / Override. Manual menu
  retained as a fallback.
- Fixes a latent bug where HARDWARE_MODULES used literal "\n" inside a
  heredoc, producing invalid Nix.

Downstream flake:
- Capture the running Nomarchy commit and pin `nomarchy.url` to it so the
  installed system can't drift onto a newer breaking main.
- Prompt for a real hostname; nixosConfigurations.<hostname> replaces the
  generic .default. networking.hostName lands in system.nix.
- Generated flake now derives a single `pkgs` from nixpkgs + Nomarchy's
  `overlays.default` and shares it between nixosSystem and the standalone
  homeManagerConfiguration so dotfile-fast-iteration with nomarchy-env-update
  stays separate from `nixos-rebuild` while still seeing Nomarchy packages.
- `nix flake lock` runs in /mnt/etc/nixos before nixos-install so first boot
  consumes the resolved set.
- Post-install, run home-manager switch inside `nixos-enter` via runuser so
  the user's first login already has dotfiles. Failure is non-fatal.

Disk layout:
- /boot bumped to 1 GiB (was 512 MiB; tight with multi-generation kernels).
- New @snapshots subvolume at /.snapshots for snapper/btrbk/rollback.
- LUKS passphrase moved from /tmp/secret.key to /dev/shm/nomarchy-luks.key
  (tmpfs), shredded after disko, LUKS_PASSWORD unset.

Branding:
- New core/system/branding.nix sets system.nixos.distroId = "nomarchy" and
  distroName = "Nomarchy". /etc/os-release now reports Nomarchy, so fastfetch
  and other os-release readers show the right name.

Cleanup:
- flake.nix exposes `overlays.default = nomarchyOverlay` for downstream use.
- Trailing duplicated `main "$@"` + orphan `}` removed from install.sh.

👑 Nomarchy

Nomarchy is a professional-grade NixOS distribution that replicates the Omarchy Wayland workflow with a strictly declarative, flake-based architecture. It provides a highly polished, "it just works" experience for power users who want a beautiful Hyprland environment without sacrificing the reliability of NixOS.

Key Features

  • Purely Declarative: Your entire desktop—themes, fonts, wallpapers, and toolchains—is defined in code.
  • Modular Merging Architecture: Distro code and user code are strictly separated. You can update the distro core without ever touching or breaking your personal configurations.
  • Interactive "Smart" Installer: Detects hardware, sets up networking, localizes timezones/keymaps, and offers multi-select software profiles.
  • Erase Your Darlings (Optional): Optional BTRFS root-wipe on boot ensures your system stays pristine and 100% declarative.
  • Dynamic Theming Engine: 20+ built-in themes with instant UI feedback via IPC (swww, waybar, and stylix).
  • Portable State (nomarchy-sync): Easily backup and sync your declarative config and dynamic state (theme/wallpaper choices) to a private Git repo.

📂 Component-Based Architecture

Nomarchy uses a Feature-Centric Directory Structure. For a comprehensive breakdown of the system architecture, folder roles, and module logic, see the Detailed Architecture Documentation.

Configuration, modules, and utilities are strictly organized to maintain sanity as the system grows.

  • core/: Foundational OS & User defaults (Bootloader, Audio, Bluetooth, core system features).
  • features/: Isolated modules containing Nix logic and raw dotfiles.
    • features/apps/: App-specific configs (e.g., features/apps/btop/, features/apps/kitty/), each containing their own default.nix and standalone config/ directory mapped via Home Manager.
    • features/desktop/: Desktop environment components (e.g., Hyprland, Waybar).
    • features/scripts/utils/: Consolidated repository for all custom Nomarchy bash scripts, centrally packaged and injected into the user's PATH with correct dependencies.
  • themes/: The global theming engine. It holds pure color data and logic. Theme-specific app layouts (like a custom Waybar layout) are stored directly inside the app's feature folder, solving the matrix problem of theming.

📥 Installation

Verify the experience without touching your hardware:

./bin/utils/nomarchy-test-installer

This builds a full graphical VM of the installer environment. Once inside, click the Install Nomarchy icon or run nomarchy-install.

2. Build the Installer ISO

To install on physical hardware, generate your own bootable image:

nix build .#nixosConfigurations.installerIso.config.system.build.isoImage

The ISO will be located at ./result/iso/nixos-*.iso. Flash it to a USB drive and boot.

3. Run the Installer

Once booted into the Live environment, launch the installer:

nomarchy-install

The wizard will guide you through:

  • Networking: An interactive wizard to connect to Wi-Fi if needed.
  • Hardware: Optimized profiles for Dell XPS, Framework, Apple T2, and more.
  • Storage: Choice between Standard Ext4 or Encrypted BTRFS with optional Impermanence.
  • Localization: Searchable timezones and keyboard layout selection.

🛠️ Configuration & Usage

Nomarchy uses a "Downstream" model. After installation, your configuration lives in /etc/nixos/ and is split into three main parts:

1. Distro Core (Upstream)

Managed via the public Git repository. This is the engine. You should generally not modify files here.

2. Your System (system.nix)

Add system-wide packages, services, and hardware tweaks here. Example: Adding a persistent directory for Docker if using Impermanence:

environment.persistence."/persist" = {
  directories = [ "/var/lib/docker" ];
};

3. Your User Environment (home.nix)

Add user-level packages, aliases, and dotfiles here. Example: Overriding the default terminal:

nomarchy.home.terminal = "kitty";

Applying Changes

After editing your files, apply them instantly. IMPORTANT: Nomarchy requires the --impure flag for evaluation. You MUST use the following aliases rather than standard NixOS commands:

sys-update  # Rebuilds the NixOS system (Runs: sudo nixos-rebuild switch --flake .#default --impure)
env-update  # Reloads your Home Manager environment (Runs: home-manager switch --flake .#default --impure)

🚀 Commands & Keybindings

Keybinding Action
Super + Space App Launcher (Walker)
Super + Shift + Space Nomarchy Menu (Walker)
Super + Ctrl + Space Background Selector (Walker)
Super + Shift + Ctrl + Space Theme Selector (Walker)
Super + Alt + Space Toggle Top Bar (Waybar)
Super + Return Open Terminal
Super + Q Close Window

Utility Scripts

Nomarchy includes dozens of productivity scripts available in your PATH. Some highlights:

  • nomarchy-sync push <repo>: Backup your setup to Git.
  • nomarchy-theme-bg-next: Cycle to the next wallpaper in the current theme.
  • nomarchy-menu: The central hub for all utilities and pickers.

Built with ❤️ using NixOS, Hyprland, Stylix, and the spirit of Omarchy.
