This is the start of my fun attempt at using NixOS containers for web
services as a Docker replacement.
After spending some time on other servers I realized that I don't
actually *need* my dotfiles on those servers, so it becomes
significantly faster to build these containers without worrying about
home-manager and command-line programs I use on the host.
Main advantages include web service configuration with Nix instead of
Docker. Disadvantages include increased complexity for anything that
isn't already maintained by others in nixpkgs.
