# PlugApps Linux Distribution Image Builder
#
# Licensed under the GPLv2.
#
# This script builds a Plugbox distribution/image.
# 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: ./distro-builder workingdir
#
# NOTE: This script is interactive.
# Agree to installing packages and answer "y" to cleaning the Pacman database.
#
# NOTE: Make sure the package "mtd-utils" is installed for making UBI images.
