Configuration files for my Nix-based devices

This repository contains the configuration files for my Nix-based devices, both Darwin and NixOS.

You can customize the configuration to your liking.

Prerequisites

Before using a NixOS or nix-darwin configuration, you need to install the prerequisites.

NixOS prerequisites nix-darwin prerequisites

# install XCode CLI tools
xcode-select --install

# install Rosetta
sudo softwareupdate --install-rosetta

# install homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# install nix
# say no when asking for determinate OS
curl -fsSL https://install.determinate.systems/nix | sh -s -- install
exec $SHELL

Installation

Homelab

Create a root password using the TTY

sudo su
passwd

Get the IP adress of the target machine

ip a

Ensure that the SSH server is running

sudo systemctl start sshd

From your host, copy your SSH keys to the server

export NIXOS_HOST=192.168.1.xxx

scp ~/.ssh/id_ed25519 root@$NIXOS_HOST:/root/

SSH into the target machine and adds keys to the SSH agent

You may need to copy keys to /mnt/root/.ssh

ssh root@$NIXOS_HOST

mkdir -p /root/.ssh
mv /root/id_ed25519 /root/.ssh/id_ed25519
chmod 700 /root/.ssh
chmod 600 /root/.ssh/id_ed25519

eval "$(ssh-agent -s)"
ssh-add /root/.ssh/id_ed25519

Install the system

nixos-install --flake "git+ssh://git@github.com/VDuchauffour/nix-config.git#sebastian"

Add user password

nixos-enter --root /mnt -c 'passwd alice'

For security, remove the keys when done

shred -u /root/.ssh/id_ed25519

Unmount the filesystems

umount -Rl "/mnt"
zpool export -a

Reboot

reboot

Set up the configuration

git clone https://github.com/VDuchauffour/nix-config.git ~/.nix-config
cd ~/.nix-config

sudo -E nix run nix-darwin -- switch --flake ~/.nix-config#tyrell
# or
sudo -E nixos-rebuild switch --flake ~/.nix-config#deckard

Post-install configuration

Logitech G Hub (nix-darwin only)

Go to System Settings > Privacy & Security and apply the following changes:

• allow Logitech G Hub to control Accessibility, Input Monitoring, and Screen & System Audio Recording.
• allow Logitech G Hub Agent to control Accessibility.

You may need to add manually the Applications to the list of allowed applications.

Misc

Use the following command to check the value of an option on your current system:

nixos-option --flake .#hostName options.path.value

Use the following command to update only the Nix-related inputs in the lock file:

nix flake update nixpkgs nixpkgs-unstable nixpkgs-nixos nix-darwin home-manager home-manager-unstable

Use the following command to list all installed packages on your machine:

nix-env -qaP
