❄️ NixOS + Darwin Config ❄️

Introduction

This is a config for multiple hosts of varying degrees of specificity, but main is an audio-oriented, modular NixOS configuration relying on Home-Manager and Flakes and includes examples of

• Custom Modules
• Custom Scripts
• Derivations
• Overlays
• DevShells

You probably won't want to try installing any of these hosts directly due to UUID discrepancies in hardware-configuration.nix, so this repo primarily serves as a reference in creating your own config

Some direct utility may be found in leveraging the binary cache by adding Garnix to your nix-config

nix.settings.substituters = [ "https://cache.garnix.io" ];
nix.settings.trusted-public-keys = [ "cache.garnix.io:CTFPyKSLcx5RMJKfLo5EEPUObbA78b0YQ2DTCJXqr9g=" ];

Special thanks to vimjoyer, ryan4yin, and PowerUser64, as their content/configs were massively helpful for learning the basics of NixOS, flakes, home-manager, and linux audio

Overview

Structure

• Firstly, pinning our system inputs, flake.nix is a parent

• Beneath this, various hosts are defined with sys and usr (think configuration.nix and home-manager.nix)

• sys and usr are further divided into modules within their corresponding directories

• Modules used by more than one host are stored in common

  flake
  ├── common
  │   ├── sys
  │   └── usr
  └── hosts
          ├── mac
          │   ├── sys
          │   └── usr
          ├── macvm
          │   ├── sys
          │   └── usr
          ├── main
          │   ├── sys
          │   └── usr
          ├── mainvm
          │   ├── sys
          │   └── usr
          └── media
              ├── sys
              └── usr
  

  usr also includes subdirectories for dotfiles, custom derivations, development environments, scripts, and theming to enable convienent access

Installation

Setup

1. Enable experimental features by adding this to /etc/nixos/configuration.nix

   # Enable flakes
   nix.settings.experimental-features = [
     "nix-command"
     "flakes"
   ];

   Then rebuild

   sudo nixos-rebuild switch

2. Move /etc/nixos to ~/etc/nixos, symlink new location to old
   Enable non-sudo config edits

   {
   mkdir ~/etc
   sudo mv /etc/nixos ~/etc/
   sudo chown -R $(id -un):users ~/etc/nixos
   sudo ln -s ~/etc/nixos /etc/
   }

3. Download repo to ~/etc/nixos

   {
   mv ~/etc/nixos ~/etc/nixos.backup
   cd ~/etc
   git clone https://github.com/camdenboren/nixos.git
   }

4. Download Notes to ~/Documents/Repos/Notes
   Not needed on mac or vm's

   {
   cd ~/Documents
   git clone https://github.com/camdenboren/Notes.git
   }

5. Update hardware UUID's in hardware-config. Use as needed
   UUID and sd* can be found in Gnome Disks

   sudo fdisk /dev/sdb
   sudo mkfs -t ext4 /dev/sdb
   sudo chown camdenboren:users ~/media -R

Rebuild

sudo nixos-rebuild boot --flake ~/etc/nixos#hostName

Freetube config won't be updated until it's been launched
So launch it, clean up config errors, restart

  [!NOTE] homebrew.greedyCasks does not seem to be working, so explicitly passing --greedy is needed (for now)

  sw
  brew upgrade --greedy
  brew cleanup

  {
  mkdir ~/vm
  cd ~/vm
  quickget windows 10
  quickget nixos 24.05 gnome
  }
