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 BASEBITSDIR="$4" 40 # This is highly x86-centric and will be used directly below. 41 bootable="-o bootimage=i386;$BASEBITSDIR/boot/cdboot -o no-emul-boot" 42 43 # Make EFI system partition (should be done with makefs in the future) 44 dd if=/dev/zero of=efiboot.img bs=4k count=200 45 device=`mdconfig -a -t vnode -f efiboot.img` 46 newfs_msdos -F 12 -m 0xf8 /dev/$device 47 mkdir efi 48 mount -t msdosfs /dev/$device efi 49 mkdir -p efi/efi/boot 50 cp -p "$BASEBITSDIR/boot/loader.efi" efi/efi/boot/bootx64.efi 51 umount efi 52 rmdir efi 53 mdconfig -d -u $device 54 bootable="$bootable -o bootimage=i386;efiboot.img -o no-emul-boot -o platformid=efi" 55 56 shift 57else 58 BASEBITSDIR="$3" 59 bootable="" 60fi 61 62if [ $# -lt 3 ]; then 63 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 64 exit 1 65fi 66 67LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 68NAME="$1"; shift 69 70publisher="The FreeBSD Project. https://www.FreeBSD.org/" 71echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" 72$MAKEFS -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$@" 73rm -f "$BASEBITSDIR/etc/fstab" 74rm -f efiboot.img 75 76if [ "$bootable" != "" ]; then 77 # Look for the EFI System Partition image we dropped in the ISO image. 78 for entry in `$ETDUMP --format shell $NAME`; do 79 eval $entry 80 if [ "$et_platform" = "efi" ]; then 81 espstart=`expr $et_lba \* 2048` 82 espsize=`expr $et_sectors \* 512` 83 espparam="-p efi::$espsize:$espstart" 84 break 85 fi 86 done 87 88 # Create a GPT image containing the partitions we need for hybrid boot. 89 imgsize=`stat -f %z "$NAME"` 90 $MKIMG -s gpt \ 91 --capacity $imgsize \ 92 -b "$BASEBITSDIR/boot/pmbr" \ 93 $espparam \ 94 -p freebsd-boot:="$BASEBITSDIR/boot/isoboot" \ 95 -o hybrid.img 96 97 # Drop the PMBR, GPT, and boot code into the System Area of the ISO. 98 dd if=hybrid.img of="$NAME" bs=32k count=1 conv=notrunc 99 rm -f hybrid.img 100fi 101
