Installation of NixOS with encrypted root

These are my notes on instaling NixOS 16.03 on a Lenovo ThinkPad X1 Carbon (4th generation) with an encrypted root file system using UEFI.

Most of this is scrambled from the following pages:

• Encrypted Root on NixOS - Nix Wiki
• Installing NixOS - Chris Martin
• Linux administration and use - Earl Douglas
• Installing NixOS on a ThinkPad W540 with encrypted root - Bluish Coder

Expression for a buildEnv-based declarative user environment

This is one way of managing your user profile declaratively.

Alternatives include:

• an attrset-based nix-env-based environment, installed using nix-env -ir rather than nix-env --set. LnL has an overlay which shows a way of doing this.
• home-manager, which provides NixOS-like config for your $HOME

Note that this is incompatible with regular imperative use of nix-env, e.g. nix-env -iA nixpkgs.hello. It has the advantage of allowing the installation of multiple outputs of the same package much better than nix-env's builtin profile builder does.

Autologin a user at the console (NixOS)

Problem

NixOS provide services.mingetty.autologinUser option, but it can’t be used for the specific TTY.

Minimal working example

TTY1 and user “guest”:

# Import python packages which are installed in the nix store

# Note you NEED this if you install it via environment.systemPackages
# E.g environment.systemPackages = with pkgs; [ python27Packages.tensorflowWithCuda ]

# You DON'T NEED this if you do it like this: 
# python-with-my-packages = pkgs.python27.withPackages (ps: with ps; [ tensorflowWithCuda]);
# environment.systemPackages = [ python-with-my-packages ]
