make-memstick.sh revision 293723 
1#!/bin/sh
2#
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>
