-# This script generates a "memstick image" for UEFI-capable systems.
-#
-# Prerequisites:
-#  - 'make release'
-#  - KERNCONF *must* be VT (or vt_efifb(4) compiled into the kernel)
-#
-# Note:  This only works for amd64, because i386 lacks the EFI boot bits.
+# 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>
