# This script generates a "memstick image" (image that can be copied to a
# USB memory stick) from a directory tree. Note that the script does not
# clean up after itself very well for error conditions on purpose so the
# problem can be diagnosed (full filesystem most likely but ...).
#
# Usage: make-memstick.sh <directory tree or manifest> <image filename>
