 3# This script generates a "memstick image" (image that can be copied to a
 4# USB memory stick) from a directory tree.  Note that the script does not
 5# clean up after itself very well for error conditions on purpose so the
 6# problem can be diagnosed (full filesystem most likely but ...).
 7#
 8# Usage: make-memstick.sh <directory tree> <image filename>
