Installation of Arch Linux on a USB stick with UEFI and legacy BIOS Support

Our goal here is to have one USB stick to rule them all. Objectives:

  • We want a full system - not a live CD
  • We want to boot this system on a Macbook Pro (requires UEFI)
  • We want to boot this system on a Acer C720 Chromebook (requires Legacy BIOS support)
  • We want the system "functional"

The last bullet is subject to interpretation, but I'm defining functional as:

  • X Windows works (with LXDE)
