Support basic nixos/configuration.nix

I'm attempting to configure an old Acer laptop that I bought at a used
electronics store in Shepherd's Bush (~100GBP) as my server. I'd like to install
NixOS on it. The configuration.nix herein defines a starting point for the
configuration for that machine. It isn't currently working.

Troubleshooting and solutions forthcoming...
