It is considered architecture dependent since each 10# platform has a slightly unique way of making bootable CDs. This script 11# is also allowed to generate any number of images since that is more of 12# publishing decision than anything else. 13# 14# Usage: 15# 16# mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir] 17# 18# Where -b is passed if the ISO image should be made "bootable" by 19# whatever standards this architecture supports (may be unsupported), 20# image-label is the ISO image label, image-name is the filename of the 21# resulting ISO image, base-bits-dir contains the image contents and 22# extra-bits-dir, if provided, contains additional files to be merged 23# into base-bits-dir as part of making the image. 24 25set -e 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 bootable=1 46 shift 47else 48 bootable="" 49fi 50 51if [ $# -lt 3 ]; then 52 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 53 exit 1 54fi 55 56LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 57NAME="$1"; shift 58# MAKEFSARG extracted already 59shift 60 61if [ -n "${METALOG}" ]; then 62 metalogfilename=$(mktemp /tmp/metalog.XXXXXX) 63 cat ${METALOG} > ${metalogfilename} 64 MAKEFSARG=${metalogfilename} 65fi 66 67if [ -n "$bootable" ]; then 68 echo "Building bootable disc" 69 70 # Apple boot code 71 uudecode -o /tmp/hfs-boot-block.bz2 "`dirname "$0"`/hfs-boot.bz2.uu" 72 bzip2 -d /tmp/hfs-boot-block.bz2 73 OFFSET=$(hd /tmp/hfs-boot-block | grep 'Loader START' | cut -f 1 -d ' ') 74 OFFSET=0x$(echo 0x$OFFSET | awk '{printf("%x\n",$1/512);}') 75 dd if="$BASEBITSDIR/boot/loader" of=/tmp/hfs-boot-block seek=$OFFSET conv=notrunc 76 77 bootable="-o bootimage=macppc;/tmp/hfs-boot-block -o no-emul-boot" 78 79 # pSeries/PAPR boot code 80 mkdir -p "$BASEBITSDIR/ppc/chrp" 81 cp "$BASEBITSDIR/boot/loader" "$BASEBITSDIR/ppc/chrp" 82 cat > "$BASEBITSDIR/ppc/bootinfo.txt" << EOF 83<chrp-boot> 84<description>FreeBSD Install</description> 85<os-name>FreeBSD</os-name> 86<boot-script>boot &device;:,\ppc\chrp\loader</boot-script> 87</chrp-boot> 88EOF 89 bootable="$bootable -o chrp-boot" 90 if [ -n "${METALOG}" ]; then 91 echo "./ppc type=dir uname=root gname=wheel mode=0755" >> ${metalogfilename} 92 echo "./ppc/chrp type=dir uname=root gname=wheel mode=0755" >> ${metalogfilename} 93 echo "./ppc/chrp/loader type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 94 echo "./ppc/bootinfo.txt type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 95 fi 96 97 # Petitboot config for PS3/PowerNV 98 echo FreeBSD Install=\'/boot/kernel/kernel vfs.root.mountfrom=cd9660:/dev/iso9660/$LABEL\' > "$BASEBITSDIR/etc/kboot.conf" 99 if [ -n "${METALOG}" ]; then 100 echo "./etc/kboot.conf type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 101 fi 102fi 103 104publisher="The FreeBSD Project. https://www.FreeBSD.org/" 105echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" 106if [ -n "${METALOG}" ]; then 107 echo "./etc/fstab type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 108fi 109makefs -D -N ${BASEBITSDIR}/etc -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$MAKEFSARG" "$@" 110rm -f "$BASEBITSDIR/etc/fstab" 111rm -f /tmp/hfs-boot-block 112rm -rf "$BASEBITSDIR/ppc" 113if [ -n "${METALOG}" ]; then 114 rm ${metalogfilename} 115fi 116
