Dustin's Nix / NixOS config

Overview

These are my "dotfiles" contained within Nix deriviations that drive setup and configuration of, as of this writing

my Macbook Pro
a NixOS workstation sitting on my desk at home
an old Thinkpad I use as an air-gapped machine
virtual machines on my home-lab Proxmox server

In a previous life my configuration was driven by Guix, but with the release of new Apple Silicon I started exploring other options. Enter Nix and NixOS.

Features

Simplicity as a guiding principle; Nix is notoriously confusing so make it easy to understand
Entirely driven by my single Flake
Supports sharing common config between an M1 Macbook Pro and NixOS PCs
Simple bash scripts to build and switch environments

Step 1 - For foreign distros (namely MacOS), install Nix package manager

Install the nix package manager:

sh <(curl -L https://nixos.org/nix/install) --daemon

nix-channel --add https://nixos.org/channels/nixpkgs-unstable nixpkgs

nix-channel --update

Step 2 - Install home-manager

Install the nix package manager:

nix-channel --add https://github.com/nix-community/home-manager/archive/master.tar.gz home-manager

nix-channel --update

Step 3 - If MacOS, install Darwin dependencies

Install nix-darwin, a native set of Nix modules for MacOS, and Xcode CLI tools.

xcode-select --install

nix-build https://github.com/LnL7/nix-darwin/archive/master.tar.gz -A installer

./result/bin/darwin-installer

Step 4 - Build the environment

Grab the latest nix-config zip file from Github, move to the directory and run

./bin/mac-build

./bin/nixos-build

Step 5 - Add Yubikey and generate key

Insert laptop Yubikey and generate private keys

ssh-keygen -t ecdsa-sk

That's it. You're done.
