Note: This repository is a manual fork of kclejeune/system that I've heavily modified. Because it's a manual fork, rebasing is often done by overlaying commits from upstream onto this repo. Many thanks and attribution to kclejeune for the original work and helping me get going with Nix, Flakes, and managing a system configuration declaratively.
This repository manages system configurations for all of my macOS, nixOS, and linux machines.
This repository is a flake. All system configurations are defined
in flake.nix. Platorm specific configurations are found defined in the flake outputs
darwinConfigurations
, nixosConfigurations
for macOS and NixOS respectively.
Nix-Darwin and NixOS configurations share as much overlap as possible in the common module, ./modules/common.nix. Platform specific modules add onto the common module in ./modules/darwin/default.nix and ./modules/nixos/default.nix for macOS and NixOS respectively.
My home-manager configuration is entirely decoupled from NixOS and nix-darwin configurations. This means that all of its modules are found in ./modules/home-manager. These modules are imported into all other configurations in the common module similarly to this:
{ config, pkgs, ... }: {
home-manager.users.edattore = import ./home-manager/home.nix;
}
This means that home.nix is fully compatible as a standalone configuration, managed with the home-manager
CLI.
This allows close replication of any user config for any linux system running nix. These configurations are defined in the homeConfigurations
output.
User "profiles" are specified in ./profiles; these modules configure contextual, identity-specific settings such as SSL certificates or work vs. personal email addresses. When possible, home-manager functionality is extracted into ./profiles/home-manager, as mentioned previously
Run the installer script to perform a multi-user installation on darwin or linux:
sh <(curl -L https://nixos.org/nix/install) --daemon
echo "experimental-features = nix-command flakes" | sudo tee -a /etc/nix/nix.conf
Note that this step is naturally skipped on NixOS since nix
is the package manager by default.
Follow the installation instructions, then run
sudo nixos-install --flake github:ELD/nix-system#indium
Clone this repository into ~/.nixpkgs
with
git clone https://github.com/ELD/nix-system ~/.nixpkgs
You can bootstrap a new nix-darwin system using
nix --extra-experimental-features "nix-command flakes" run github:ELD/nix-system#sysdo -- bootstrap --darwin
or a home-manager configuration using
nix --extra-experimental-features "nix-command flakes" develop -c sysdo bootstrap --home-manager
The sysdo
utility is a python script that wraps nix
, darwin-rebuild
, nixos-rebuild
,
and home-manager
commands to provide a consistent interface across multiple platforms. It has some dependencies which are defined in the devShell
flake output. Documentation for this tool is found in sysdo.md.
