# 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.

## VM installation

This allows you to setup a VM with minimal effort.
However this requires some prerequisites.

- A VM running the minimal NixOS ISO reachable with SSH under nixos@nixos.2li.local.
- The VM runs UEFI.
- You've set a password for the nixos user.

1. `./scripts/install_new_vm.sh`
2. Provide the required information and wait until the script is finished.
3. Reboot and profit!

## Raspberry Pi installation

1. Add the new system to `flake.nix`.
2. Build the image with `scripts/build-raspi-image.sh SYSTEMNAME`
3. Flash the image to an SD card
   `dd if=~/Downloads/SYSTEMNAME.img of=/dev/mmcblk0 bs=4M`.
4. After you've booted the Pi get the new SSH key with `ssh-keyscan
    hostname.custom.domain` and add it to `scrts/secrets.nix`.
5. Then login into the new Pi and mount the `FIRMWARE` partition with
   `sudo mkdir -p /mnt && sudo mount /dev/disk/by-label/FIRMWARE /mnt` and make
   sure that your `config.txt` looks like [./systems/raspi4/config.txt](./systems/raspi4/config.txt)
6. Change the password

## x86 installation

1. `curl https://git.2li.ch/Nebucatnetzer/nixos/archive/master.tar.gz | tar xz`
2. `cd nixos && nix-shell`
3. `sudo python3 scripts/format-disk.py`
4. `sudo nixos-install --no-root-passwd --root /mnt --impure --flake .#SYSTEMNAME`

## Update remote systems

Simply run the script `scripts/update_all_systems.xsh` and it will iterate over
all defined systems.
The script requires Xonsh but can be easily adapted to BASH or similar.

## Non-Nixos System

1. `scripts/install-home-manager.sh`
