#NOTE: you do not actually need the boot loader in normal use because it is
# *not* overwritten by a standard upslug upgrade, so you can make an image with
# just non-LinkSys software which can be flashed into the NSLU2.  Because
# LinkSys have made "EraseAll" available, however, (this does overwrite RedBoot)
# it is a bad idea to produce flash images without a valid RedBoot - that allows
# an innocent user upgrade attempt to instantly brick the NSLU2.
