Psst: I can help write Nix at your company. Get in touch.

Hey, you made it! Welcome. 🤓

You've stumbled upon my personal journey with Nix. For over a year, I've been hacking away at this configuration. This repository drives my office PC, M1 Macbook, and virtual machines in my home lab. Along with syncthing to manage data, this Nix configuration guarantees I have a working, seamless experience across each machine I use.

While developing, I've done my best to keep it simple - for both future me and readers like you. You'll see that in how I've organized code, as I keep filename conventions the same across modules. To get started, you can bootstrap from bare metal, run on your Mac, or try out a live ISO. See below.

• Multiple Nix and NixOS configurations across Mac and Linux, including desktop, laptop, server
• A single nix-command to start from zero, both x86 and MacOS platforms
• Fully declarative MacOS dock and MacOS App Store apps
• 100% flake driven, no use of channels or configuration.nix during install or after
• Fully managed, auto-updating homebrew environment (yes, Nix manages homebrew!)
• Easily share config across Linux and Mac with both Nix and Home Manager
• Bleeding edge Emacs that fixes itself, thanks to a community overlay
• Extensively configured NixOS environment including clean aesthetic + window animations
• Auto-loading of Nix overlays: drop a file in a dir and it runs (great for patches!)
• Large Emacs literate configuration to explore (if that's your thing)
• Optimized for simplicity and readability in all cases, not small files spread across collections of modules

• ✅ Persistence defined under XDG (#5)
• Opt-in persistence using impermanence and zfs snapshot reset (#8)
• Secrets managed with sops-nix (#6)

You can edit your configuration and save the changes.

./result/sw/bin/darwin-rebuild switch --flake .#Dustins-MBP --impure && \
unlink ./result

sudo nixos-rebuild switch --flake .#felix
