# 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> <image filename>
