NixOS

My NixOS configuration I use as my every day system.

nixpkgs - git Channel

In nix repo add nixpkgs channel as submodule:

git submodule add https://github.com/nixos/nixpkgs

Add channels repo as upstream and fetch:

cd nixpkgs
git remote add channels https://github.com/nixos/nixpkgs-channels
git fetch

Go to branch of choice:

git remote update channels
git reset  --hard channels/nixos-17.03

Set location to directory in config:

nix.nixPath = [
    "/etc/nixos"
    "nixpkgs=/etc/nixos/nixpkgs"
    "nixos-config=/etc/nixos/configuration.nix"
];
