#
# This script is used by release/Makefile to build the (optional) ISO images
# for a FreeBSD release.  It is considered architecture dependent since each
# platform has a slightly unique way of making bootable CDs.  This script
# is also allowed to generate any number of images since that is more of
# publishing decision than anything else.
#
# Usage:
#
# mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir]
#
# Where -b is passed if the ISO image should be made "bootable" by
# whatever standards this architecture supports (may be unsupported),
# image-label is the ISO image label, image-name is the filename of the
# resulting ISO image, base-bits-dir contains the image contents and
# extra-bits-dir, if provided, contains additional files to be merged
# into base-bits-dir as part of making the image.

if [ "$1" = "-b" ]; then
	# Apple boot code
	uudecode -o /tmp/hfs-boot-block.bz2 "`dirname "$0"`/hfs-boot.bz2.uu"
	bzip2 -d /tmp/hfs-boot-block.bz2
	OFFSET=$(hd /tmp/hfs-boot-block | grep 'Loader START' | cut -f 1 -d ' ')
	OFFSET=0x$(echo 0x$OFFSET | awk '{printf("%x\n",$1/512);}')
	dd if="$4/boot/loader" of=/tmp/hfs-boot-block seek=$OFFSET conv=notrunc

	bootable="-o bootimage=macppc;/tmp/hfs-boot-block -o no-emul-boot"
