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 vianixos-rebuild --flake
- Home-manager configuration on
home.nix
, accessible viahome-manager --flake
- Basic boilerplate for adding custom packages (under
pkgs
) and overlays (underoverlays
). Acessible on your system, home config, as well asnix 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
- Clone this repo to somewhere acessible (i usually have a
/dotfiles
folder for this) - Add stuff you currently have on
/etc/nixos/configuration.nix
toconfiguration.nix
, and/etc/nixos/hardware-configuration.nix
tohardware-configuration.nix
- If you're already using home-manager, add your stuff from
~/.config/nixpkgs/home.nix
tohome.nix
- Take a look at
flake.nix
, filling out stuff marked byTODO
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.
Customize your home-manager configuration
Use the home.nix
file.
For a list of options, see man home-configuration.nix
. Also see the manual.
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.
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.
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.
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.
