  • A Deep Dive Into Nixos: from Configuration to Boot CS5250: Advanced Operating Systems
    A Deep Dive into NixOS: From Configuration To Boot CS5250: Advanced Operating Systems Chen Jingwen A0111764L National University of Singapore Abstract Mature operating systems (e.g. Windows, Fedora) are inherently stateful and imperative, adding layers of complexity by installing or upgrading software. This causes side-effects such as breaking existing software while upgrading shared libraries without maintaining backwards compatibility. NixOS is a Linux distribution designed to be purely functional, where building everything from the kernel to the web browser has no side- effects. System configuration files are written in the Nix language, a lazy functional domain specific language with a declarative syntax, and software packages are managed by the Nix package manager. A distinct feature of NixOS is the ability to declare the configuration of an entire system in one file, which is then used to build a bootable system deterministically. This report gives an overview and the motivations of NixOS, and a deep dive into how the configuration of an operating system can be derived from a single file. 1 Contents 1 Introduction 4 2 Motivation 5 2.1 Multiple versions . 5 2.2 Destructive updates . 5 2.3 Rollback difficulties . 6 2.4 Non-atomic upgrades . 6 2.5 Inability to reproduce builds . 6 3 NixOS Architecture 7 3.1 Package specifications and the Nix expression language . 7 3.1.1 Nix expression language . 8 3.1.2 Derivations . 9 3.2 Nix store . 9 3.2.1 Cryptographic hash . 9 3.2.2 Source to binary deployment . 10 3.2.3 Nix database . 10 3.3 Nix package manager .

    1 WHAT ’ S IN THIS CHAPTER? ➤ Installing and getting started with Visual Studio Code ➤ Understanding the cross-platform components that make up Visual Studio Code GETTING STARTED The choice of the editor used by any developer is an incredibly personal one. The reason to pick one over the rest depends on a collection of attributes typically related to the tasks they perform on a daily basis. Developers look for functionality, keystroke shortcuts, code snippets, colora- tions, and more that allow them to stay productive. Dislodging developers from their choice is not easy. Any change in editors is going to result in an immediate loss of productivity. After all, it takes time to become familiar with the features offered and have them become a natural part of the coding “flow.” As a result, it takes a special level of “better” for a developer to switch editors. For this reason, the success of Visual Studio Code speaks volumes for its features and function- ality. Although it has been officially released for just three years (it left public preview in April 2016), it has quickly become one of the top editors in terms of popularity, competing with Sublime Text, Atom,COPYRIGHTED and UltraEdit for the top spot. MATERIAL But that doesn ’ t matter to you, the reader. What you care about more is what Visual Studio Code can do to help you be productive. As a developer, it is frequently the small things that make the biggest difference—knowing how to add code with a single keyboard chord, being able to do client and server debugging on your Node.js project, or language-sensitive code completion.
