It uses hfsutils (emulators/hfsutils) to generate a template 5# filesystem with the relevant interesting files. These are then found by 6# grep, and the offsets written to a Makefile snippet. 7# 8# Because of licensing concerns, and because it is overkill, we do not 9# distribute hfsutils as a build tool. If you need to regenerate the HFS 10# template (e.g. because the boot block or the CHRP script have grown), 11# you must install it from ports. 12 13HFS_SIZE=400 #Size in 2048-byte blocks of the produced image 14LOADER_SIZE=500k 15 16# Generate 800K HFS image 17OUTPUT_FILE=hfs-boot 18 19dd if=/dev/zero of=$OUTPUT_FILE bs=2048 count=$HFS_SIZE 20hformat -l "FreeBSD Install" $OUTPUT_FILE 21hmount $OUTPUT_FILE 22 23# Create and bless a directory for the boot loader 24hmkdir ppc 25hattrib -b ppc 26hcd ppc 27 28# Make the CHRP boot script, which gets loader from the ISO9660 partition 29cat > bootinfo.txt << EOF 30<CHRP-BOOT> 31<DESCRIPTION>FreeBSD/powerpc bootloader</DESCRIPTION> 32<OS-NAME>FreeBSD</OS-NAME> 33<VERSION> $FreeBSD: head/stand/powerpc/boot1.chrp/bootinfo.txt 184490 2008-10 34-31 00:52:31Z nwhitehorn $ </VERSION> 35 36<COMPATIBLE> 37MacRISC MacRISC3 MacRISC4 38</COMPATIBLE> 39<BOOT-SCRIPT> 40" screen" output 41boot &device;:,\ppc\loader &device;:0 42</BOOT-SCRIPT> 43</CHRP-BOOT> 44EOF 45echo 'Loader START' | dd of=loader.tmp cbs=$LOADER_SIZE count=1 conv=block 46 47hcopy bootinfo.txt :bootinfo.txt 48hcopy loader.tmp :loader 49hattrib -c chrp -t tbxi bootinfo.txt 50humount 51 52rm bootinfo.txt 53rm loader.tmp 54 55bzip2 $OUTPUT_FILE 56echo 'HFS boot filesystem created by generate-hfs.sh' > $OUTPUT_FILE.bz2.uu 57echo 'DO NOT EDIT' >> $OUTPUT_FILE.bz2.uu 58 59uuencode $OUTPUT_FILE.bz2 $OUTPUT_FILE.bz2 >> $OUTPUT_FILE.bz2.uu 60rm $OUTPUT_FILE.bz2 61 62
