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 make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi 68 bootable="$bootable -o bootimage=i386;${espfilename} -o no-emul-boot -o platformid=efi" 69 70 shift 71else 72 bootable="" 73fi 74 75if [ $# -lt 3 ]; then 76 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 77 exit 1 78fi 79 80LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 81NAME="$1"; shift 82# MAKEFSARG extracted already 83shift 84 85publisher="The FreeBSD Project. https://www.FreeBSD.org/" 86echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" 87if [ -n "${METALOG}" ]; then 88 metalogfilename=$(mktemp /tmp/metalog.XXXXXX) 89 cat ${METALOG} > ${metalogfilename} 90 echo "./etc/fstab type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 91 MAKEFSARG=${metalogfilename} 92fi 93$MAKEFS -D -N ${BASEBITSDIR}/etc -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$MAKEFSARG" "$@" 94rm -f "$BASEBITSDIR/etc/fstab" 95rm -f ${espfilename} 96if [ -n "${METALOG}" ]; then 97 rm ${metalogfilename} 98fi 99 100if [ "$bootable" != "" ]; then 101 # Look for the EFI System Partition image we dropped in the ISO image. 102 for entry in `$ETDUMP --format shell $NAME`; do 103 eval $entry 104 if [ "$et_platform" = "efi" ]; then 105 espstart=`expr $et_lba \* 2048` 106 espsize=`expr $et_sectors \* 512` 107 espparam="-p efi::$espsize:$espstart" 108 break 109 fi 110 done 111 112 # Create a GPT image containing the partitions we need for hybrid boot. 113 hybridfilename=$(mktemp /tmp/hybrid.img.XXXXXX) 114 if [ "$(uname -s)" = "Linux" ]; then 115 imgsize=`stat -c %s "$NAME"` 116 else 117 imgsize=`stat -f %z "$NAME"` 118 fi 119 $MKIMG -s gpt \ 120 --capacity $imgsize \ 121 -b "$BASEBITSDIR/boot/pmbr" \ 122 -p freebsd-boot:="$BASEBITSDIR/boot/isoboot" \ 123 $espparam \ 124 -o $hybridfilename 125 126 # Drop the PMBR, GPT, and boot code into the System Area of the ISO. 127 dd if=$hybridfilename of="$NAME" bs=32k count=1 conv=notrunc 128 rm -f $hybridfilename 129fi 130
