+# Creates an ext2 filesystem on a USB stick for testing with OFW
+#
+# Instructions for use:
+# - copy this file and ext2test.fth to a Linux machine
+# - turn off X with 'telinit 4',
+# - ensure that no USB stick is mounted
+# - insert USB stick, wait seven seconds settling time,
+# - execute this script "ext2test.sh /dev/sda",
+# - remove USB stick,
+# - insert in test laptop,
+# - power up,
+# - examine output.
