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}/../scripts/tools.subr 25. ${scriptdir}/../../tools/boot/install-boot.sh 26 27if [ "$1" = "-b" ]; then 28 MAKEFSARG="$4" 29else 30 MAKEFSARG="$3" 31fi 32 33if [ -f ${MAKEFSARG} ]; then 34 BASEBITSDIR=`dirname ${MAKEFSARG}` 35 METALOG=${MAKEFSARG} 36elif [ -d ${MAKEFSARG} ]; then 37 BASEBITSDIR=${MAKEFSARG} 38 METALOG= 39else 40 echo "${MAKEFSARG} must exist" 41 exit 1 42fi 43 44if [ "$1" = "-b" ]; then 45 # Make an EFI system partition. 46 espfilename=$(mktemp /tmp/efiboot.XXXXXX) 47 # ESP file size in KB. 48 espsize="2048" 49 make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi 50 51 bootable="-o bootimage=efi;${espfilename} -o no-emul-boot -o platformid=efi" 52 53 shift 54else 55 bootable="" 56fi 57 58if [ $# -lt 3 ]; then 59 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 60 exit 1 61fi 62 63LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 64NAME="$1"; shift 65# MAKEFSARG extracted already 66shift 67 68publisher="The FreeBSD Project. https://www.FreeBSD.org/" 69echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" 70if [ -n "${METALOG}" ]; then 71 metalogfilename=$(mktemp /tmp/metalog.XXXXXX) 72 cat ${METALOG} > ${metalogfilename} 73 echo "./etc/fstab type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 74 MAKEFSARG=${metalogfilename} 75fi 76$MAKEFS -D -N ${BASEBITSDIR}/etc -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$MAKEFSARG" "$@" 77rm -f "$BASEBITSDIR/etc/fstab" 78rm -f ${espfilename} 79if [ -n "${METALOG}" ]; then 80 rm ${metalogfilename} 81fi 82 83if [ "$bootable" != "" ]; then 84 # Look for the EFI System Partition image we dropped in the ISO image. 85 for entry in `$ETDUMP --format shell $NAME`; do 86 eval $entry 87 # XXX: etdump(8) returns "default" for the initial entry 88 if [ "$et_platform" = "default" ]; then 89 espstart=`expr $et_lba \* 2048` 90 espsize=`expr $et_sectors \* 512` 91 espparam="-p efi::$espsize:$espstart" 92 break 93 fi 94 done 95 96 # Create a GPT image containing the EFI partition. 97 efifilename=$(mktemp /tmp/efi.img.XXXXXX) 98 if [ "$(uname -s)" = "Linux" ]; then 99 imgsize=`stat -c %s "$NAME"` 100 else 101 imgsize=`stat -f %z "$NAME"` 102 fi 103 $MKIMG -s gpt \ 104 --capacity $imgsize \ 105 $espparam \ 106 -o $efifilename 107 108 # Drop the GPT into the System Area of the ISO. 109 dd if=$efifilename of="$NAME" bs=32k count=1 conv=notrunc 110 rm -f $efifilename 111fi 112
