#!/bin/sh

#It is assumed you will need at the most 3 partitions: /, /boot and /home. It is also
#assumed that you want partitions to be mounted at /mnt and so forth. Edit it as you
#see fit. Further it is to be noted that this script assumes a BIOS installation. Edit it if you
#you want, however it would make more sense to use the official installer that is packaged with
#Arch Linux for a UEFI install.
