# Nix Starter Config
|
|
|
|
This is a minimal (yet complete) nix flake for getting started with NixOS + home-manager.
|
|
|
|
## What this provides
|
|
|
|
- NixOS configuration on `configuration.nix`, accessible via `nixos-rebuild --flake`
|
|
- Home-manager configuration on `home.nix`, accessible via `home-manager --flake`
|
|
- Basic boilerplate for adding custom packages (under `pkgs`) and overlays (under `overlays`). Acessible on your system, home config, as well as `nix build .#package-name`
|
|
- Boilerplate for custom NixOS (`modules/nixos`) and home-manager (`modules/home-manager`) modules
|
|
- Dev shell for bootstrapping, accessible via `nix develop`
|
|
|
|
## Getting started
|
|
|
|
Assuming you have a basic NixOS installation up and running:
|
|
|
|
### The repo
|
|
- [Install git](https://nixos.wiki/wiki/git)
|
|
- Clone this repo to somewhere acessible (i usually have a `/dotfiles` folder for this)
|
|
- Add stuff you currently have on `/etc/nixos/configuration.nix` to `configuration.nix`, and `/etc/nixos/hardware-configuration.nix` to `hardware-configuration.nix`
|
|
- If you're already using home-manager, add your stuff from `~/.config/nixpkgs/home.nix` to `home.nix`
|
|
- Take a look at `flake.nix`, filling out stuff marked by `TODO`s
|
|
- Create a remote repo (github, gitlab, sr.ht, etc) and push your changes for safekeeping
|
|
|
|
### Bootstrapping
|
|
- Run `nix develop --experimental-features "nix-command flakes"` to bootstrap into flake-enabled nix and home-manager.
|
|
- Run `sudo nixos-rebuild switch --flake .` to apply system configuration
|
|
- Run `home-manager switch --flake .` to apply home configuration
|
|
- Reboot!
|
|
|
|
### How to's
|
|
|
|
#### Customize your NixOS configuration
|
|
|
|
Use the `configuration.nix` file.
|
|
|
|
For a list of options, see `man configuration.nix`. Also see [the manual](https://nixos.org/manual/nixos/stable/index.html#ch-configuration).
|
|
|
|
### Customize your home-manager configuration
|
|
|
|
Use the `home.nix` file.
|
|
|
|
For a list of options, see `man home-configuration.nix`. Also see [the manual](https://rycee.gitlab.io/home-manager/index.html#ch-usage).
|
|
|
|
|
|
### Adding packages
|
|
|
|
Create a folder inside `pkgs`, and add a `default.nix` file containing a derivation. Be sure to also `callPackage` them on `pkgs/default.nix`.
|
|
|
|
See [the manual](https://nixos.org/manual/nixpkgs/stable/).
|
|
|
|
### Adding overlays
|
|
|
|
Use the `overlays/default.nix` file. If it gets too big, feel free to split it up.
|
|
|
|
If you're applying patches, i recommend you keep the patches on the `overlays` folder as well.
|
|
|
|
See [the wiki article](https://nixos.wiki/wiki/Overlays).
|
|
|
|
### Adding your own modules
|
|
|
|
Create a file for them on either `modules/nixos` or `modules/home-manager`. Be sure to also add them to the listing at `modules/nixos/default.nix` or `modules/home-manager/default.nix`.
|
|
|
|
See [the wiki article](https://nixos.wiki/wiki/Module).
|
|
|
|
### Adding more hosts or users, or multiple files
|
|
|
|
If you're starting to manage more than one host or user (or splitting up a big configuration in multiple files), you might want to create a `hosts` and/or `users` folder, and move your configs there. Be sure to change the path on `flake.nix` as well.
