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 27scriptdir=$(dirname $(realpath $0)) 28. ${scriptdir}/../scripts/tools.subr 29 30if [ "$1" = "-b" ]; then 31 MAKEFSARG="$4" 32else 33 MAKEFSARG="$3" 34fi 35 36if [ -f ${MAKEFSARG} ]; then 37 BASEBITSDIR=`dirname ${MAKEFSARG}` 38 METALOG=${MAKEFSARG} 39elif [ -d ${MAKEFSARG} ]; then 40 BASEBITSDIR=${MAKEFSARG} 41 METALOG= 42else 43 echo "${MAKEFSARG} must exist" 44 exit 1 45fi 46 47if [ "$1" = "-b" ]; then 48 bootable=1 49 shift 50else 51 bootable="" 52fi 53 54if [ $# -lt 3 ]; then 55 echo "Usage: $0 [-b] image-label image-name base-bits-dir [extra-bits-dir]" 56 exit 1 57fi 58 59LABEL=`echo "$1" | tr '[:lower:]' '[:upper:]'`; shift 60NAME="$1"; shift 61# MAKEFSARG extracted already 62shift 63 64if [ -n "${METALOG}" ]; then 65 metalogfilename=$(mktemp /tmp/metalog.XXXXXX) 66 cat ${METALOG} > ${metalogfilename} 67 MAKEFSARG=${metalogfilename} 68fi 69 70if [ -n "$bootable" ]; then 71 echo "Building bootable disc" 72 73 BOOTBLOCK=$(mktemp /tmp/hfs-boot-block.XXXXXX) 74 75 # Apple boot code 76 uudecode -p "`dirname "$0"`/hfs-boot.bz2.uu" | bunzip2 > $BOOTBLOCK 77 OFFSET=$(hd $BOOTBLOCK | grep 'Loader START' | cut -f 1 -d ' ') 78 OFFSET=0x$(echo 0x$OFFSET | awk '{printf("%x\n",$1/512);}') 79 dd if="$BASEBITSDIR/boot/loader" of=$BOOTBLOCK seek=$OFFSET conv=notrunc 80 81 bootable="-o bootimage=macppc;$BOOTBLOCK -o no-emul-boot" 82 83 # pSeries/PAPR boot code 84 mkdir -p "$BASEBITSDIR/ppc/chrp" 85 cp "$BASEBITSDIR/boot/loader" "$BASEBITSDIR/ppc/chrp" 86 cat > "$BASEBITSDIR/ppc/bootinfo.txt" << EOF 87<chrp-boot> 88<description>FreeBSD Install</description> 89<os-name>FreeBSD</os-name> 90<boot-script>boot &device;:,\ppc\chrp\loader</boot-script> 91</chrp-boot> 92EOF 93 bootable="$bootable -o chrp-boot" 94 if [ -n "${METALOG}" ]; then 95 echo "./ppc type=dir uname=root gname=wheel mode=0755" >> ${metalogfilename} 96 echo "./ppc/chrp type=dir uname=root gname=wheel mode=0755" >> ${metalogfilename} 97 echo "./ppc/chrp/loader type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 98 echo "./ppc/bootinfo.txt type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 99 fi 100 101 # Petitboot config for PS3/PowerNV 102 echo FreeBSD Install=\'/boot/kernel/kernel vfs.root.mountfrom=cd9660:/dev/iso9660/$LABEL\' > "$BASEBITSDIR/etc/kboot.conf" 103 if [ -n "${METALOG}" ]; then 104 echo "./etc/kboot.conf type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 105 fi 106fi 107 108publisher="The FreeBSD Project. https://www.FreeBSD.org/" 109echo "/dev/iso9660/$LABEL / cd9660 ro 0 0" > "$BASEBITSDIR/etc/fstab" 110if [ -n "${METALOG}" ]; then 111 echo "./etc/fstab type=file uname=root gname=wheel mode=0644" >> ${metalogfilename} 112fi 113${MAKEFS} -D -N ${BASEBITSDIR}/etc -t cd9660 $bootable -o rockridge -o label="$LABEL" -o publisher="$publisher" "$NAME" "$MAKEFSARG" "$@" 114rm -f "$BASEBITSDIR/etc/fstab" 115if [ -n "$bootable" ]; then 116 rm $BOOTBLOCK 117fi 118rm -rf "$BASEBITSDIR/ppc" 119if [ -n "${METALOG}" ]; then 120 rm ${metalogfilename} 121fi 122
