driverOS

This repository contains the entirety of my operating system, all my used applications, my dotfiles and my custom app themes.

Huh?

• Nix is a package manager for Linux systems. It's purely functional: It treats packages as immutable, which brings a few advantages like having the ability to install multiple versions of packages at the same time, and atomic upgrades & rollbacks. All package definitions are written in a functional language called Nix.

• NixOS is an operating system built entirely with Nix. The complete operating system is built from a declarative Nix config: With the advantage of all configuration being defined in a single place, distribution becomes easy. With NixOS, you also gain all the advantages of Nix: You can roll back faulty system configurations and test changes to your OS before you deploy them.

You can read more about NixOS here.

Highlights

• Multiple OS configurations, for my laptop & workstation
• Fully declarative config for my daily drivers
  • hyprland / eww / rofi / dunst, alacritty / nushell / starship, intellij, gtk / qt, syncthing, greetd, wayland, zathura
• User & Global packages managed with the same config
• Consistent declarative config for wallpaper & color theme
• Project Templates with nix flakes included

Installation

You can install this on any computer that runs NixOS with flake support enabled. (Obviously, some settings are OS- & hardware-specific, so it's probably better if you integrate relevant settings into your own config.)

1. Clone the repository.
2. Run sudo nixos-rebuild switch --flake '.#<hostname>'
   • Optionally, link the flake.nix with ln -s <repository-flake-path> /etc/nixos/flake.nix so that future rebuilds use the repository automatically.
3. Done!

All application settings are managed declaratively, except for:

• IntelliJ IDEA which uses settings sync.
• Firefox which has account sync.
• Private SSH Keys, which can't be easily managed with a public git repo.

Templates

This repository also provides custom-made flake templates for languages & environments I commonly use.

To use, register flake.nix in the nix registry:

nix registry add home <path-to-repository>

At which point you can start using the templates:

nix flake init -t home#rust
