It is considered architecture dependent since each 10# platform has a slightly unique way of making bootable CDs. This script 11# is also allowed to generate any number of images since that is more of 12# publishing decision than anything else. 13# 14# Usage: 15# 16# mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir] 17# 18# Where -b is passed if the ISO image should be made "bootable" by 19# whatever standards this architecture supports (may be unsupported), 20# image-label is the ISO image label, image-name is the filename of the 21# resulting ISO image, base-bits-dir contains the image contents and 22# extra-bits-dir, if provided, contains additional files to be merged 23# into base-bits-dir as part of making the image. 24 25set -e 26 27scriptdir=$(dirname $(realpath $0)) 28. ${scriptdir}/../scripts/tools.subr 29. ${scriptdir}/../../tools/boot/install-boot.sh 30 31if [ "$1" = "-b" ]; then 32 MAKEFSARG="$4" 33else 34 MAKEFSARG="$3" 35fi 36 37if [ -f ${MAKEFSARG} ]; then 38 BASEBITSDIR=`dirname ${MAKEFSARG}` 39 METALOG=${MAKEFSARG} 40elif [ -d ${MAKEFSARG} ]; then 41 BASEBITSDIR=${MAKEFSARG} 42 METALOG= 43else 44 echo "${MAKEFSARG} must exist" 45 exit 1 46fi 47 48if [ "$1" = "-b" ]; then 49 # This is highly x86-centric and will be used directly below. 50 bootable="-o bootimage=i386;$BASEBITSDIR/boot/cdboot -o no-emul-boot" 51 52 # Make EFI system partition. 53 espfilename=$(mktemp /tmp/efiboot.XXXXXX) 54 # ESP file size in KB. 55 espsize="2048" 56 if [ -f "${BASEBITSDIR}/boot/loader_ia32.efi" ]; then 57 extra_args="${BASEBITSDIR}/boot/loader_ia32.efi bootia32" 58 fi 59 make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi bootx64 ${extra_args} 60 bootable="$bootable -o bootimage=i386;${espfilename} -o no-emul-boot -o platformid=efi" 61 62 shift 63else 64 bootable="" 65fi 66 67if [ $# -lt 3 ]; then 68 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 69 exit 1 70fi 71 72LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 73NAME="$1"; shift 74# MAKEFSARG extracted already 75shift 76 77publisher="The FreeBSD Project. https://www.FreeBSD.org/" 78echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" 79if [ -n "${METALOG}" ]; then 80 metalogfilename=$(mktemp /tmp/metalog.XXXXXX) 81 cat ${METALOG} > ${metalogfilename} 82 echo "./etc/fstab type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 83 MAKEFSARG=${metalogfilename} 84fi 85$MAKEFS -D -N ${BASEBITSDIR}/etc -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$MAKEFSARG" "$@" 86rm -f "$BASEBITSDIR/etc/fstab" 87rm -f ${espfilename} 88if [ -n "${METALOG}" ]; then 89 rm ${metalogfilename} 90fi 91 92if [ "$bootable" != "" ]; then 93 # Look for the EFI System Partition image we dropped in the ISO image. 94 for entry in `$ETDUMP --format shell $NAME`; do 95 eval $entry 96 if [ "$et_platform" = "efi" ]; then 97 espstart=`expr $et_lba \* 2048` 98 espsize=`expr $et_sectors \* 512` 99 espparam="-p efi::$espsize:$espstart" 100 break 101 fi 102 done 103 104 # Create a GPT image containing the partitions we need for hybrid boot. 105 hybridfilename=$(mktemp /tmp/hybrid.img.XXXXXX) 106 if [ "$(uname -s)" = "Linux" ]; then 107 imgsize=`stat -c %s "$NAME"` 108 else 109 imgsize=`stat -f %z "$NAME"` 110 fi 111 $MKIMG -s gpt \ 112 --capacity $imgsize \ 113 -b "$BASEBITSDIR/boot/pmbr" \ 114 -p freebsd-boot:="$BASEBITSDIR/boot/isoboot" \ 115 $espparam \ 116 -o $hybridfilename 117 118 # Drop the PMBR, GPT, and boot code into the System Area of the ISO. 119 dd if=$hybridfilename of="$NAME" bs=32k count=1 conv=notrunc 120 rm -f $hybridfilename 121fi 122
