== Pidora 2014 Reformating Boot Partition Script ==
#!/bin/bash
#
# Script to take an SD card image created by Livemedia-Creator (such as for a
# Raspberry Pi) with a ext4 boot partition and reformat it vfat.
#
# To use this script, provide the image name as
# the first argument.
# Example "./revfat image-name.img"
#
# Requirements (Fedora 17 package):
# bash (bash)
# fdisk (util-linux)
