HakaseOS

A modular, flake-based NixOS configuration for a single host (hakase). Heavily inspired by OmarchyOS.

Features

• Hyprland compositor with UWSM (systemd session management)
• Matugen for automatic system-wide theming from wallpaper colors
• Multi-monitor support for intuitive desktop management
• Hardened Firefox with custom bookmarks and new tab page
• Vim keybindings throughout the system
• SOPS for encrypted secrets management
• CachyOS kernel via chaotic-nyx for performance optimizations

🚧 TODO

• LUKS designed
