In order to install NixOS behind corporate proxy do the usual stuff but before running nixos-install set this environment variable:

export CURL_NIX_FLAGS="-x http://user:password@proxy:port/"

In addition in case you have ties to cloning from GitHub (like vim plugins), you should export proxy related variables:

export HTTP_PROXY=http://user:password@proxy:port/

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
