My NixOS configuration

NixOS

Installation (assuming host config already exists)

# All as root
HOST=...  # set host variable to use proper configuration

nix-shell
git clone https://this.repo.url/ /etc/nixos
cd /etc/nixos
sudo nixos-install --root /mnt --impure --flake .#$HOST

# Reboot

System update

# Go to the repo directory
sudo nixos-rebuild switch --flake .

Non-NixOS

Example steps necessary to bootstrap and use this configuration on Ubuntu.

In WSL2

We strongly recommend enabling systemd, then installing Nix as normal:

Installation

First make sure, your user is in the sudo/wheel group.

# Install git, curl and xz (e.g. for ubuntu)
sudo apt install git xz-utils curl

# Clone this repository
git clone https://github.com/iancleary/nixos-config.git
cd nixos-config

# Install nix (determinate-systems installation)
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

# Open tempoary shell with nix and home-manager (shell.nix)
nix-shell

# Remove nix (this is necessary, so home-manager can install nix)
nix-env -e nix

# Install the configuration (adjust to the configuration you want to use )
home-manager switch --flake .#wsl

# Exit temporary shell
exit

# Set zsh (installed by nix) as default shell
echo ~/.nix-profile/bin/zsh | sudo tee -a /etc/shells
usermod -s ~/.nix-profile/bin/zsh $USER

Update

# Go to the repo directory
home-manager switch --flake .
