[Nix-dev] undefined variable 'config', in '/etc/nixos/configuration.nix'

[Marc Weber]

Hy Bryan,

nixos-hardware-scan > /etc/nixos/configuration.nix

This line should be the first line (hardware-scan is outdated)
> {config, pkgs, ...}:

The manual contains all info you need:
http://hydra.nixos.org/build/479665/download/1/nixos/manual.html

Take the fileSystems section from there.

Note: there is a svn repo called configurations containing many advanced
examples.

I'm still puzzled about the error. Can you try whether the error goes
away when using output of nixos-hardware-scan ?
