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 [ "$1" = "-b" ]; then 27 # This is highly x86-centric and will be used directly below. 28 bootable="-o bootimage=i386;$4/boot/cdboot -o no-emul-boot" 29 30 # Make EFI system partition (should be done with makefs in the future) 31 dd if=/dev/zero of=efiboot.img bs=4k count=200 32 device=`mdconfig -a -t vnode -f efiboot.img` 33 newfs_msdos -F 12 -m 0xf8 /dev/$device 34 mkdir efi 35 mount -t msdosfs /dev/$device efi 36 mkdir -p efi/efi/boot 37 cp "$4/boot/loader.efi" efi/efi/boot/bootx64.efi 38 umount efi 39 rmdir efi 40 mdconfig -d -u $device 41 bootable="$bootable -o bootimage=i386;efiboot.img -o no-emul-boot -o platformid=efi" 42 43 shift 44else 45 bootable="" 46fi 47 48if [ $# -lt 3 ]; then 49 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 50 exit 1 51fi 52 53LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 54NAME="$1"; shift 55 56publisher="The FreeBSD Project. https://www.FreeBSD.org/" 57echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$1/etc/fstab" 58makefs -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$@" 59rm -f "$1/etc/fstab" 60rm -f efiboot.img 61 62if [ "$bootable" != "" ]; then 63 # Look for the EFI System Partition image we dropped in the ISO image. 64 for entry in `etdump --format shell $NAME`; do 65 eval $entry 66 if [ "$et_platform" = "efi" ]; then 67 espstart=`expr $et_lba \* 2048` 68 espsize=`expr $et_sectors \* 512` 69 espparam="-p efi::$espsize:$espstart" 70 break 71 fi 72 done 73 74 # Create a GPT image containing the partitions we need for hybrid boot. 75 imgsize=`stat -f %z $NAME` 76 mkimg -s gpt \ 77 --capacity $imgsize \ 78 -b $4/boot/pmbr \ 79 $espparam \ 80 -p freebsd-boot:=$4/boot/isoboot \ 81 -o hybrid.img 82 83 # Drop the PMBR, GPT, and boot code into the System Area of the ISO. 84 dd if=hybrid.img of=$NAME bs=32k count=1 conv=notrunc 85 rm -f hybrid.img 86fi 87
