Want to use Nix for development but you're not sure how? Concerned about the
fluidity of nixpkgs channels or not being able to easily install arbitrary
package versions?

| # You will learn why `make` is so great, and why, despite its "weird" syntax, | |
| # it is actually a highly expressive, efficient, and powerful way to build | |
| # programs. | |

My experiments with an XMonad setup in NixOS. This is my work box now, so it pretty much works.
probably needs:
# useradd -m iain
# passwd iain ...
# passwd root ...
