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