# 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 [ "x$1" = "x-b" ]; then
	# This is highly x86-centric and will be used directly below.
	bootable="-o bootimage=i386;$4/boot/cdboot -o no-emul-boot"

	# Make EFI system partition (should be done with makefs in the future)
	dd if=/dev/zero of=efiboot.img bs=4k count=100
	device=`mdconfig -a -t vnode -f efiboot.img`
	newfs_msdos -F 12 -m 0xf8 /dev/$device
	mkdir efi
	mount -t msdosfs /dev/$device efi
	mkdir -p efi/efi/boot
	cp "$4/boot/loader.efi" efi/efi/boot/bootx64.efi
