It is considered architecture dependent since each 11# platform has a slightly unique way of making bootable CDs. This script 12# is also allowed to generate any number of images since that is more of 13# publishing decision than anything else. 14# 15# Usage: 16# 17# mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir] 18# 19# Where -b is passed if the ISO image should be made "bootable" by 20# whatever standards this architecture supports (may be unsupported), 21# image-label is the ISO image label, image-name is the filename of the 22# resulting ISO image, base-bits-dir contains the image contents and 23# extra-bits-dir, if provided, contains additional files to be merged 24# into base-bits-dir as part of making the image. 25 26set -e 27 28scriptdir=$(dirname $(realpath $0)) 29. ${scriptdir}/../../tools/boot/install-boot.sh 30 31if [ -z $ETDUMP ]; then 32 ETDUMP=etdump 33fi 34 35if [ -z $MAKEFS ]; then 36 MAKEFS=makefs 37fi 38 39if [ -z $MKIMG ]; then 40 MKIMG=mkimg 41fi 42 43if [ "$1" = "-b" ]; then 44 BASEBITSDIR="$4" 45 # This is highly x86-centric and will be used directly below. 46 bootable="-o bootimage=i386;$BASEBITSDIR/boot/cdboot -o no-emul-boot" 47 48 # Make EFI system partition. 49 espfilename=$(mktemp /tmp/efiboot.XXXXXX) 50 # ESP file size in KB. 51 espsize="2048" 52 make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi 53 bootable="$bootable -o bootimage=i386;${espfilename} -o no-emul-boot -o platformid=efi" 54 55 shift 56else 57 BASEBITSDIR="$3" 58 bootable="" 59fi 60 61if [ $# -lt 3 ]; then 62 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 63 exit 1 64fi 65 66LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 67NAME="$1"; shift 68 69publisher="The FreeBSD Project. https://www.FreeBSD.org/" 70echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" 71$MAKEFS -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$@" 72rm -f "$BASEBITSDIR/etc/fstab" 73rm -f ${espfilename} 74 75if [ "$bootable" != "" ]; then 76 # Look for the EFI System Partition image we dropped in the ISO image. 77 for entry in `$ETDUMP --format shell $NAME`; do 78 eval $entry 79 if [ "$et_platform" = "efi" ]; then 80 espstart=`expr $et_lba \* 2048` 81 espsize=`expr $et_sectors \* 512` 82 espparam="-p efi::$espsize:$espstart" 83 break 84 fi 85 done 86 87 # Create a GPT image containing the partitions we need for hybrid boot. 88 imgsize=`stat -f %z "$NAME"` 89 $MKIMG -s gpt \ 90 --capacity $imgsize \ 91 -b "$BASEBITSDIR/boot/pmbr" \ 92 $espparam \ 93 -p freebsd-boot:="$BASEBITSDIR/boot/isoboot" \ 94 -o hybrid.img 95 96 # Drop the PMBR, GPT, and boot code into the System Area of the ISO. 97 dd if=hybrid.img of="$NAME" bs=32k count=1 conv=notrunc 98 rm -f hybrid.img 99fi 100
