NixOS-install-notes

* Installed per https://chris-martin.org/2015/installing-nixos
  but without the encrypted partition
    * Instead of DEVICE=/dev/mapper/enc-pv
    * rather DEVICE=/dev/sda3
    * pvcreate $DEVICE
    * vgcreate vg $DEVICE

* Couldn't get wpa_supplicant to work from the install environment,
  so before doing... $ nixos-install
  * cabled into to internet gateway
  * replaced...
        networking.wireless.enable = true;
    with...
        networking.networkmanager.enable = true;
    Not sure if needed to include...
         environment.systemPackages... i
                networkmanager networkmanagerapplet
  * enabled graphical environment (alternatively test if nmcli works without)

  * After install, for development (to build PDFium)...
      environment.systemPackages = with pkgs; [
        stdenv
        git
        clang
        python

* mkdir -p ~/Repos/PDFium & cd ~Repos/PDFium

* Copied depot_tools from backup
  and added to .bashrc...

* Install PDFium depot_tools
  git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

* Hack workaround to "/bin/bash: bad interpreter: No such file or directory"
  $ sudo ln -s `which bash` /bin/bash

* SideNote: Was having a problem with .cipd_client not found when running gclient.
  Traced this down to `update_depot_tools` not working due to .cipd_client not being found.
  Initially bypasses setting DEPOT_TOOLS_UPDATE=0 in bash environment,
  but when I checked later .cipd_client appeared.  Maybe I recloned depot_tools
  in the middle and that fixed something.

* Get the code (https://pdfium.googlesource.com/pdfium/)
  $ mkdir repo
  $ cd repo
