Jovian-NixOS is a NixOS overlay and module collection that enables running NixOS on the Steam Deck and similar handheld gaming devices. It provides hardware-specific kernel configurations, firmware update integration, Steam Deck UI (Gaming Mode) support, audio/display driver patches, and a suite of system services (power management, input handling, performance control) modeled after SteamOS. The repository is structured as a Nix flake with a clear separation of concerns: NixOS modules under `modules/` define configuration options for Steam Deck hardware, Steam client integration, and SteamOS-like system settings; a Nix overlay under `pkgs/` provides patched or vendored packages (gamescope, mesa, linux kernel, pipewire, etc.) that are not yet in upstream Nixpkgs or require Steam Deck-specific modifications. The codebase demonstrates strong NixOS engineering practices: modular design, extensive use of lib.mkIf/mkMerge for conditional configuration, hardcoded path patching via replaceVars, and resholve for shell script safety. The documentation system is a custom Ruby pipeline that generates a static site from markdown with options and package listings. While the repository is tightly coupled to NixOS and the Steam Deck domain, it is a well-maintained, production-quality example of how to extend NixOS for specialized hardware.
Bazzite is a custom Fedora Atomic (Silverblue/Kinoite) operating system image optimized for gaming on desktops, handheld PCs (Steam Deck, ROG Ally, etc.), and HTPCs. It provides a SteamOS-like experience with pre-installed gaming tools (MangoHud, vkBasalt, OBS VkCapture), hardware support (OGC kernel, HDR/VRR, DisplayLink, per-device audio profiles), and a suite of system management utilities. The repository is not a traditional application but a build system for generating container images and ISOs. The architecture is container-native: images are built via Containerfile and GitHub Actions, with modular overlays for different variants (desktop, deck, nvidia) and desktop environments (GNOME, KDE). Key components include a justfile recipe library for user-facing configuration (ujust), systemd services, udev rules, RPM spec files with patches for upstream packages (BlueZ, UPower, Xwayland, MangoHud), and hardware detection scripts. The build process is fully automated via CI/CD, with image signing and attestation. The project is actively maintained with a large community and extensive hardware support.
This repository contains a comprehensive set of Bash scripts to automate the installation and configuration of the Hyprland window manager on Arch Linux, along with associated desktop components (waybar, rofi, sddm, pipewire, fonts, GTK themes, etc.). The main entry point is `install.sh`, which presents an interactive whiptail-based menu to let users select desired features (NVIDIA setup, Bluetooth, Thunar, ZSH, dotfiles, etc.). It orchestrates over 30 modular sub-scripts in `install-scripts/` that handle package installation via pacman and AUR helpers, service enabling, configuration file copying (including the popular KooL Hyprland dotfiles from a separate repository), and system modifications. The codebase is well-structured for its purpose: it uses a centralized logging system, progress indicators, and a global functions library (`Global_functions.sh`) that encapsulates package installation and error handling. Additional utility scripts provide battery, disk, and temperature monitoring as optional systemd user services. The project is actively maintained with changelog updates and issue templates, though it is tightly coupled to the Arch Linux ecosystem and the KooL Hyprland dotfiles. It is not a reusable library but serves as a polished, user-friendly deployment tool for end-users.
NixBSD is a declarative system configuration framework that ports NixOS infrastructure to BSD kernels (FreeBSD and OpenBSD). It functions as a complete operating system distribution definition, managing bootloaders, init systems, services, and user configurations through Nix expressions. The architecture is modular, leveraging the NixOS module system to define system state, with specific adaptations for BSD-specific tools like rc.d, jails, and ZFS. The system relies heavily on custom build logic to generate disk images, installers, and bootloader configurations that are compatible with BSD hardware constraints. It includes a portable init abstraction layer to unify service management across Linux, FreeBSD, and OpenBSD, though this introduces significant complexity. Security features like PAM, ACME certificates, and setuid wrappers are implemented as declarative modules. While the codebase demonstrates high craftsmanship in system integration and Nix expression patterns, it suffers from high technical drift due to the inherent divergence between NixOS (systemd-based) and BSD (rc-based) ecosystems. Upstream NixOS changes frequently require manual merging, and BSD-specific logic (e.g., initware, stand-freebsd) creates maintenance bottlenecks. It is a robust infrastructure tool for users requiring declarative BSD management but requires significant expertise to maintain.
A La Carchy is a two-panel TUI (Terminal User Interface) application for Omarchy Linux that serves as a system debloater and optimizer. It provides an interactive interface for removing preinstalled applications and web apps, configuring system settings (keybindings, display, appearance, etc.), managing ASUS ROG hardware controls, applying themes from wallpaper colors, installing community themes, and backing up/restoring configurations. The architecture is a single bash script that implements a sophisticated terminal UI with guided dialogs for complex configurations, direct modification of system configuration files with safety features like backups and confirmations, and integration with Omarchy-specific utilities and standard Linux tools.
