Bulletproof Arch

• Original Author: @altercation (And an evolved Arch Wiki version of this, here)
• Contributing Author: @craSH

These are working notes on the installation of Arch Linux. I've just completed this install on a notebook (@altercation: Lenovo P50. @craSH: Dell XPS 13" 9380) but the setup should work for most laptop/desktop configurations.

Some assumptions/notes:

1. This isn't a dual boot configuration. I can see some of the appeal and still work in Adobe from time to time, but given the increasing complexity of EFI and the way Windows/MS manhandles the EFI partition during upgrades, I really would recommend steering clear of dual boot. Just my two cents here.
