nixos

This repository contains my configuration for my Nixos systems. I don't provide any garantuees that it will work on other systems. In addition some of the scripts required for installation will destroy your data when used.

Preparation

On a PC you don't have to do anything special.

For a Raspberry Pi you need to prepare the SD card first with a UEFI partition. On a PC navigate into this project and run the following commands:

nix-shell
sudo create-uefi-partition.sh

This will format the SD card at /dev/mmcblk0, create a partition and download and copy all the required files for running UEFI on a Pi 4.

Installation

Insert an USB stick with the latest NixOS ISO into your device.
curl https://git.2li.ch/Nebucatnetzer/nixos/archive/master.tar.gz | tar xz
cd nixos && nix-shell setup-shell.nix
For a normal PC run: sudo ./scripts/format-disk.py on a Raspberry Pi 4 run: sudo ./scripts/format-sdcard.py
sudo nixos-install --no-root-passwd --root /mnt --impure --flake .#SYSTEMNAME

When everything is finished you can reboot the system and remove the USB stick. You have now a fully encrypted NixOS system.

Update remote systems

Simply run the script scripts/remote_switch.sh and it will iterate over all defined systems. With the option -r the systems will reboot as well.

Non-Nixos System

scripts/install-home-manager.sh

Development

Options template

{ config, lib, pkgs, ... }:
let
  cfg = config.programs.NAME;
in
{
  options = {
    programs.NAME.enable = lib.mkEnableOption "DESCRIPTION";
  };

  config = lib.mkIf cfg.enable {
  };
}
