====== dertasiu's Arch Linux Install Script ======
This is a pretty nice set of scripts (install and post install) for installing Arch. I've tested them and I think they work fairly well, though I would like to tailor them to the way I do things. I am listing them on LJCK so if their github page goes down I still have them. If I make any changes I'll probably fork them to my own gi thub.
