I've recently been experimenting with [NixOS](https://nixos.org/) and I've found it really interesting, so I wrote a tutorial on how to install and run NixOS using Vagrant. Includes instructions for running on both macOS and Ubuntu, but should work on most operating systems.
Maybe someone else will find NixOS as interesting as I have. 🙂 I appreciate any and all feedback on the tutorial and the blog. Thanks! 🙂
