#!/bin/sh # # Module: mkisoimages.sh # Author: Jordan K Hubbard # Date: 22 June 2001 # # $FreeBSD$ # # 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. set -e scriptdir=$(dirname $(realpath $0)) . ${scriptdir}/../../tools/boot/install-boot.sh if [ -z $ETDUMP ]; then ETDUMP=etdump fi if [ -z $MAKEFS ]; then MAKEFS=makefs fi if [ -z $MKIMG ]; then MKIMG=mkimg fi if [ "$1" = "-b" ]; then BASEBITSDIR="$4" # This is highly x86-centric and will be used directly below. bootable="-o bootimage=i386;$BASEBITSDIR/boot/cdboot -o no-emul-boot" # Make EFI system partition. espfilename=$(mktemp /tmp/efiboot.XXXXXX) # ESP file size in KB. espsize="2048" make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi bootable="$bootable -o bootimage=i386;${espfilename} -o no-emul-boot -o platformid=efi" shift else BASEBITSDIR="$3" bootable="" fi if [ $# -lt 3 ]; then echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" exit 1 fi LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift NAME="$1"; shift publisher="The FreeBSD Project. https://www.FreeBSD.org/" echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" $MAKEFS -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$@" rm -f "$BASEBITSDIR/etc/fstab" rm -f ${espfilename} if [ "$bootable" != "" ]; then # Look for the EFI System Partition image we dropped in the ISO image. for entry in `$ETDUMP --format shell $NAME`; do eval $entry if [ "$et_platform" = "efi" ]; then espstart=`expr $et_lba \* 2048` espsize=`expr $et_sectors \* 512` espparam="-p efi::$espsize:$espstart" break fi done # Create a GPT image containing the partitions we need for hybrid boot. imgsize=`stat -f %z "$NAME"` $MKIMG -s gpt \ --capacity $imgsize \ -b "$BASEBITSDIR/boot/pmbr" \ -p freebsd-boot:="$BASEBITSDIR/boot/isoboot" \ $espparam \ -o hybrid.img # Drop the PMBR, GPT, and boot code into the System Area of the ISO. dd if=hybrid.img of="$NAME" bs=32k count=1 conv=notrunc rm -f hybrid.img fi
