# This script sets the boot flag for partitions whose method is
# newworld.  It removes it for all non-newworld partitions that
# have been made bootable by this script.
#
# It doesn't remove it for all non-newworld partitions: although I
# don't know of a reason to make a partition other than Apple_Bootstrap
# bootable, removing boot flags might be a bit hostile if there are
# cases I don't know about.
#
# The number of this script (currently 21) must be greater than the
# number of the script update.d/bootable (currently 20).
