Nix config

My configuration flake for NixOS, macOS, WSL2 and other Linux distributions with Nix package manager implementation installed.

Prerequisites

A Nix package manager implementaion is required. On non-NixOS systems, the prefered method to install a Nix implementation is the Lix installer.

You can install Lix using the aforementioned Lix installer:

curl --proto '=https' --tlsv1.2 -sSf -L https://install.lix.systems/lix | sh -s -- install

• To bypass the confirmation step of the installer, append --no-confirm.

• To install without systemd init system, append linux --init none on Linux or --init none on WSL2.

NixOS Installation #TODO

Boot an NixOS installer ISO image.

Create, format and mount needed partitions.

Encrypted root setup

• create root and boot partitions (swap optional)

• format the root partition with the luks structure

cryptsetup luksFormat /dev/sdx3

• open the encrypted partition and map it to /dev/mapper/cryptroot

cryptsetup luksOpen /dev/sdx3 cryptroot

• format cryptroot

mkfs.ext4 -L nixos /dev/mapper/cryptroot

• mount encrypted root

mount /dev/disk/by-label/nixos /mnt

• create boot directory in root

mkdir /mnt/boot

• mount boot partition to boot directory

mount /dev/sda1 /mnt/boot

• generate hardware-config.nix

nixos-generate-config --root /mnt --dir path/to/nixos-config/hosts/HOST

Generate hardware-configuration.nix in ./host/<host>

cd <repo>

$ nixos-install --flake .#<host>

macOS

You install nix-dawin by running:

nix run nix-darwin -- switch --flake .#darwin-arm

• Change darwin-arm to your prefered darwinConfiguration host or create a new host using the entries in hosts/generics/darwin as template.
• After installing nix-darwin, you can run update to apply changes to your system.

Uninstalling

(macOS only) Remove nix-darwin first by running:

nix run nix-darwin#darwin-uninstaller

You can remove a lix-installer-installed Nix by running:

/nix/lix-installer uninstall
