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. Download the image from: https://hydra.nixos.org/job/nixos/release-22.05/nixos.sd_image.aarch64-linux
2. Extract it with: unzstd nixos-sd-image-*-aarch64-linux.img.zst
3. Flash it to the SD card with sudo dd if=$(ls nixos-sd-image-*-aarch64-linux.img) of=/dev/mmcblk0 bs=4M
4. After booting create a password for the nixos user.
5. SSH into the system.
6. curl https://git.2li.ch/Nebucatnetzer/nixos/archive/master.tar.gz | tar xz
7. sudo cp nixos/systems/raspi4/init_config.nix /etc/nixos/configuration.nix
8. sudo nixos-rebuild switch
9. Mount the FIRMWARE partition sudo mount /dev/disk/by-label/FIRMWARE /mnt and make sure that your config.txt looks like ./systems/raspi4/config.txt
10. Install the system ./scripts/install_new_system.sh

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
