# This script creates a live image for a Slackware OS.
# Features:
# - boots using isolinux/extlinux
# - requires kernel >= 4.0 which supports multiple lower layers in overlay
# - uses squashfs to create compressed modules out of directory trees
# - uses overlayfs to bind multiple squashfs modules together
# - you can add your own modules into ./addons/ subdirectory
