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}/../../tools/boot/install-boot.sh 29 30if [ -z $ETDUMP ]; then 31 ETDUMP=etdump 32fi 33 34if [ -z $MAKEFS ]; then 35 MAKEFS=makefs 36fi 37 38if [ -z $MKIMG ]; then 39 MKIMG=mkimg 40fi 41 42if [ "$1" = "-b" ]; then 43 MAKEFSARG="$4" 44else 45 MAKEFSARG="$3" 46fi 47 48if [ -f ${MAKEFSARG} ]; then 49 BASEBITSDIR=`dirname ${MAKEFSARG}` 50 METALOG=${MAKEFSARG} 51elif [ -d ${MAKEFSARG} ]; then 52 BASEBITSDIR=${MAKEFSARG} 53 METALOG= 54else 55 echo "${MAKEFSARG} must exist" 56 exit 1 57fi 58 59if [ "$1" = "-b" ]; then 60 # This is highly x86-centric and will be used directly below. 61 bootable="-o bootimage=i386;$BASEBITSDIR/boot/cdboot -o no-emul-boot" 62 63 # Make EFI system partition. 64 espfilename=$(mktemp /tmp/efiboot.XXXXXX) 65 # ESP file size in KB. 66 espsize="2048" 67 if [ -f "${BASEBITSDIR}/boot/loader_ia32.efi" ]; then 68 make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi bootx64 \ 69 ${BASEBITSDIR}/boot/loader_ia32.efi bootia32 70 else 71 make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi 72 fi 73 bootable="$bootable -o bootimage=i386;${espfilename} -o no-emul-boot -o platformid=efi" 74 75 shift 76else 77 bootable="" 78fi 79 80if [ $# -lt 3 ]; then 81 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 82 exit 1 83fi 84 85LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 86NAME="$1"; shift 87# MAKEFSARG extracted already 88shift 89 90publisher="The FreeBSD Project. https://www.FreeBSD.org/" 91echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" 92if [ -n "${METALOG}" ]; then 93 metalogfilename=$(mktemp /tmp/metalog.XXXXXX) 94 cat ${METALOG} > ${metalogfilename} 95 echo "./etc/fstab type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 96 MAKEFSARG=${metalogfilename} 97fi 98$MAKEFS -D -N ${BASEBITSDIR}/etc -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$MAKEFSARG" "$@" 99rm -f "$BASEBITSDIR/etc/fstab" 100rm -f ${espfilename} 101if [ -n "${METALOG}" ]; then 102 rm ${metalogfilename} 103fi 104 105if [ "$bootable" != "" ]; then 106 # Look for the EFI System Partition image we dropped in the ISO image. 107 for entry in `$ETDUMP --format shell $NAME`; do 108 eval $entry 109 if [ "$et_platform" = "efi" ]; then 110 espstart=`expr $et_lba \* 2048` 111 espsize=`expr $et_sectors \* 512` 112 espparam="-p efi::$espsize:$espstart" 113 break 114 fi 115 done 116 117 # Create a GPT image containing the partitions we need for hybrid boot. 118 hybridfilename=$(mktemp /tmp/hybrid.img.XXXXXX) 119 if [ "$(uname -s)" = "Linux" ]; then 120 imgsize=`stat -c %s "$NAME"` 121 else 122 imgsize=`stat -f %z "$NAME"` 123 fi 124 $MKIMG -s gpt \ 125 --capacity $imgsize \ 126 -b "$BASEBITSDIR/boot/pmbr" \ 127 -p freebsd-boot:="$BASEBITSDIR/boot/isoboot" \ 128 $espparam \ 129 -o $hybridfilename 130 131 # Drop the PMBR, GPT, and boot code into the System Area of the ISO. 132 dd if=$hybridfilename of="$NAME" bs=32k count=1 conv=notrunc 133 rm -f $hybridfilename 134fi 135
