OS dotfiles for Nix(OS)

This repository configures all of my digital devices that run ✨ Nix(OS) ✨ !

Help

This repository can be useful if you're relatively experienced with NixOS and are looking for inspiration. If you are a complete beginner, I recommend looking elsewhere first:

Structure

Hosts

A machine, such as a server or laptop, is called a host.

Host configurations live in the hosts directory.

If a host is using NixOS, the configuration of a host is comprised of three parts:

1. a hardware configuration
2. a system configuration
3. a home configuration

If a host is using MacOS, the configuration is comprised only of a home configuration.

All of these files are imported by ./flake.nix.

System services, apps, ...

Software installed on a system-level is configured in sys. All files here are NixOS modules and their configuration options are namespaced under skogsbrus. Hosts declare and configure their system modules in ./hosts/<hostname>/system.nix.

User services, apps, ...

Software and configuration files in user-land live in home and is configured by Home Manager and are for the most part also NixOS modules.

Adding a new device

1. Add it to flake.nix.
2. Add a new folder in hosts with a hardware, system, and home configuration.
3. Run make.
4. Done!

Note that the hostname of the new device must match the name of the host in ./flake.nix.

MacOS specifics

For MacOS devices, some caveats apply. To set up my repository for compatibility with MacOS, I followed this excellent blog post: https://xyno.space/post/nix-darwin-introduction.
