# Arch Linux ARM Chroot Builder
#
# Licensed under the GPLv2.
#
# This script builds an Arch Linux ARM chroot.
# It does not include a kernel or other "low-level" components.
# First, it downloads and installs packages to the workingdir,
# then configures some basics, sets the root password to "root",
# and then creates a rootts.tar.gz and/or a UBI image, ready to flash.
#
# Usage: ./chroot-builder workingdir
#
# NOTE: This script is interactive.
# Agree to installing packages and answer "y" to cleaning the Pacman database.
