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 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 # This is highly x86-centric and will be used directly below. 40 bootable="-o bootimage=i386;$4/boot/cdboot -o no-emul-boot" 41 42 # Make EFI system partition (should be done with makefs in the future) 43 dd if=/dev/zero of=efiboot.img bs=4k count=200 44 device=`mdconfig -a -t vnode -f efiboot.img` 45 newfs_msdos -F 12 -m 0xf8 /dev/$device 46 mkdir efi 47 mount -t msdosfs /dev/$device efi 48 mkdir -p efi/efi/boot 49 cp "$4/boot/loader.efi" efi/efi/boot/bootx64.efi 50 umount efi 51 rmdir efi 52 mdconfig -d -u $device 53 bootable="$bootable -o bootimage=i386;efiboot.img -o no-emul-boot -o platformid=efi" 54 55 shift 56else 57 bootable="" 58fi 59 60if [ $# -lt 3 ]; then 61 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 62 exit 1 63fi 64 65LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 66NAME="$1"; shift 67 68publisher="The FreeBSD Project. https://www.FreeBSD.org/" 69echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$1/etc/fstab" 70$MAKEFS -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$@" 71rm -f "$1/etc/fstab" 72rm -f efiboot.img 73 74if [ "$bootable" != "" ]; then 75 # Look for the EFI System Partition image we dropped in the ISO image. 76 for entry in `$ETDUMP --format shell $NAME`; do 77 eval $entry 78 if [ "$et_platform" = "efi" ]; then 79 espstart=`expr $et_lba \* 2048` 80 espsize=`expr $et_sectors \* 512` 81 espparam="-p efi::$espsize:$espstart" 82 break 83 fi 84 done 85 86 # Create a GPT image containing the partitions we need for hybrid boot. 87 imgsize=`stat -f %z $NAME` 88 $MKIMG -s gpt \ 89 --capacity $imgsize \ 90 -b $4/boot/pmbr \ 91 $espparam \ 92 -p freebsd-boot:=$4/boot/isoboot \ 93 -o hybrid.img 94 95 # Drop the PMBR, GPT, and boot code into the System Area of the ISO. 96 dd if=hybrid.img of=$NAME bs=32k count=1 conv=notrunc 97 rm -f hybrid.img 98fi 99
