It is considered architecture dependent since each 6# platform has a slightly unique way of making bootable CDs. This script is 7# also allowed to generate any number of images since that is more of 8# publishing decision than anything else. 9# 10# Usage: 11# 12# mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir] 13# 14# Where -b is passed if the ISO image should be made "bootable" by 15# whatever standards this architecture supports (may be unsupported), 16# image-label is the ISO image label, image-name is the filename of the 17# resulting ISO image, base-bits-dir contains the image contents and 18# extra-bits-dir, if provided, contains additional files to be merged 19# into base-bits-dir as part of making the image. 20 21set -e 22 23scriptdir=$(dirname $(realpath $0)) 24. ${scriptdir}/../../tools/boot/install-boot.sh 25 26if [ -z $ETDUMP ]; then 27 ETDUMP=etdump 28fi 29 30if [ -z $MAKEFS ]; then 31 MAKEFS=makefs 32fi 33 34if [ -z $MKIMG ]; then 35 MKIMG=mkimg 36fi 37 38if [ "$1" = "-b" ]; then 39 MAKEFSARG="$4" 40else 41 MAKEFSARG="$3" 42fi 43 44if [ -f ${MAKEFSARG} ]; then 45 BASEBITSDIR=`dirname ${MAKEFSARG}` 46 METALOG=${MAKEFSARG} 47elif [ -d ${MAKEFSARG} ]; then 48 BASEBITSDIR=${MAKEFSARG} 49 METALOG= 50else 51 echo "${MAKEFSARG} must exist" 52 exit 1 53fi 54 55if [ "$1" = "-b" ]; then 56 # Make an EFI system partition. 57 espfilename=$(mktemp /tmp/efiboot.XXXXXX) 58 # ESP file size in KB. 59 espsize="2048" 60 make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi 61 62 bootable="-o bootimage=efi;${espfilename} -o no-emul-boot -o platformid=efi" 63 64 shift 65else 66 bootable="" 67fi 68 69if [ $# -lt 3 ]; then 70 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 71 exit 1 72fi 73 74LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 75NAME="$1"; shift 76# MAKEFSARG extracted already 77shift 78 79publisher="The FreeBSD Project. https://www.FreeBSD.org/" 80echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" 81if [ -n "${METALOG}" ]; then 82 metalogfilename=$(mktemp /tmp/metalog.XXXXXX) 83 cat ${METALOG} > ${metalogfilename} 84 echo "./etc/fstab type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 85 MAKEFSARG=${metalogfilename} 86fi 87$MAKEFS -D -N ${BASEBITSDIR}/etc -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$MAKEFSARG" "$@" 88rm -f "$BASEBITSDIR/etc/fstab" 89rm -f ${espfilename} 90if [ -n "${METALOG}" ]; then 91 rm ${metalogfilename} 92fi 93 94if [ "$bootable" != "" ]; then 95 # Look for the EFI System Partition image we dropped in the ISO image. 96 for entry in `$ETDUMP --format shell $NAME`; do 97 eval $entry 98 # XXX: etdump(8) returns "default" for the initial entry 99 if [ "$et_platform" = "default" ]; then 100 espstart=`expr $et_lba \* 2048` 101 espsize=`expr $et_sectors \* 512` 102 espparam="-p efi::$espsize:$espstart" 103 break 104 fi 105 done 106 107 # Create a GPT image containing the EFI partition. 108 efifilename=$(mktemp /tmp/efi.img.XXXXXX) 109 if [ "$(uname -s)" = "Linux" ]; then 110 imgsize=`stat -c %s "$NAME"` 111 else 112 imgsize=`stat -f %z "$NAME"` 113 fi 114 $MKIMG -s gpt \ 115 --capacity $imgsize \ 116 $espparam \ 117 -o $efifilename 118 119 # Drop the GPT into the System Area of the ISO. 120 dd if=$efifilename of="$NAME" bs=32k count=1 conv=notrunc 121 rm -f $efifilename 122fi 123
