Hi, I hope this is not considered thread-highjacking but it sort of fits into this thread, so here it goes:
I'm trying to follow these instructions to build a live CD based on 4.0 stable: http://www.onlamp.com/pub/a/bsd/2005/07/14/openbsd_live.html I'm in trouble when building the RAMDISK kernel with the modified Makefile.inc: cd /usr/src/distrib/i386/ramdisk_cd && make make stops with an error because it tries to copy too much into a mounted device with too little space: #######make output####### ... rm -f bsd ld -Ttext 0xD0200120 -e start -N -S -x -o bsd ${SYSTEM_OBJ} vers.o text data bss dec hex 4730816 2163584 867984 7762384 7671d0 cp /usr/src/distrib/i386/ramdisk_cd/../../../sys/arch/i386/compile/RAMDISK_CD/bsd bsd cc -DDEBUG -o rdsetroot /usr/src/distrib/i386/ramdisk_cd/../../common/elfrdsetroot.c cp bsd bsd.rd /usr/src/distrib/i386/ramdisk_cd/rdsetroot bsd.rd < mr.fs segment 0 rd_root_size_off = 0x490740 rd_root_image_off = 0x490760 rd_root_size val: 0x001DB000 (3800 blocks) copying root image... ...copied 1945600 bytes cp bsd.rd bsd.strip strip -s -R .comment -K cngetc bsd.strip gzip -c9 bsd.strip > bsd.gz dd if=/dev/zero of=/var/tmp/image.27740 bs=10k count=288 288+0 records in 288+0 records out 2949120 bytes transferred in 0.271 secs (10881719 bytes/sec) vnconfig -v -c svnd0 /var/tmp/image.27740 svnd0: 2949120 bytes on /var/tmp/image.27740 disklabel -w -r svnd0 floppy288 newfs -m 0 -o space -i 524288 -c 80 /dev/rsvnd0a /dev/rsvnd0a: 5760 sectors in 80 cylinders of 2 tracks, 36 sectors 2.8MB in 1 cyl groups (80 c/g, 2.81MB/g, 32 i/g) super-block backups (for fsck -b #) at: 32, mount /dev/svnd0a /mnt cp /usr/mdec/boot /usr/src/distrib/i386/ramdisk_cd/boot strip -s -R .comment -K cngetc /usr/src/distrib/i386/ramdisk_cd/boot dd if=/usr/src/distrib/i386/ramdisk_cd/boot of=/mnt/boot bs=512 77+1 records in 77+1 records out 39572 bytes transferred in 0.016 secs (2371001 bytes/sec) dd if=bsd.gz of=/mnt/bsd bs=512 /mnt: write failed, file system is full dd: /mnt/bsd: No space left on device 5601+0 records in 5600+0 records out 2867200 bytes transferred in 1.233 secs (2324260 bytes/sec) *** Error code 1 Stop in /usr/src/distrib/i386/ramdisk_cd (line 30 of /usr/src/distrib/i386/ramdisk_cd/../common/Makefile.inc). ######################### I haven't really understood what the 2.8MB device is for regarding the whole process. Can anybody explain and propose a solution? Can't I just copy the stuff to another device, that's bigger? If this is just for creating a floppy image that's bootable and is insignificant regarding my live CD, can I just delete these instructions from Makefile.inc? The instructions by Kevin Lo say: In the /usr/src/distrib/i386/ramdisk_cd directory, copy the two files bsd and cdrom36.fs to the /livecd directory. The cdrom36.fs in my case would be cdrom40.fs and has a fliesize bigger than 2.8MB anyway? I'm not able to spot any reference to any cdrom{version}.fs file being created in the Makefile.inc. What's "my problem"? Since I haven't been able to apply the patch to /usr/src/distrib/i386/common/Makefile.inc with "patch" I deleted the lines with a "-" in front of it in the patch file and added the lines with the "+" at the appropriate lines. Just to avoid simple mistakes, I'll include the whole Makefile.inc here. Sorry, if this is not appropriate. ########Makefile.inc########## # $OpenBSD: Makefile.inc,v 1.15 2004/11/25 22:02:08 deraadt Exp $ TOP= ${.CURDIR}/.. .include "${TOP}/Makefile.inc" IMAGE= mr.fs CBIN?= instbin CRUNCHCONF?= ${CBIN}.conf LISTS?= ${.CURDIR}/../common/list UTILS?= ${.CURDIR}/../../miniroot MOUNT_POINT= /mnt MTREE= ${UTILS}/mtree.conf XNAME?= floppy FS?= ${XNAME}${REV}.fs VND?= svnd0 VND_DEV= /dev/${VND}a VND_RDEV= /dev/r${VND}a VND_CRDEV= /dev/r${VND}c PID!= echo $$$$ REALIMAGE!= echo /var/tmp/image.${PID} BOOT= ${DESTDIR}/usr/mdec/boot FLOPPYSIZE?= 144 FLOPPYTYPE?= floppy3 all: ${FS} ${FS}: bsd.gz dd if=/dev/zero of=${REALIMAGE} bs=10k count=${FLOPPYSIZE} vnconfig -v -c ${VND} ${REALIMAGE} disklabel -w -r ${VND} ${FLOPPYTYPE} newfs -m 0 -o space -i 524288 -c 80 ${VND_RDEV} mount ${VND_DEV} ${MOUNT_POINT} cp ${BOOT} ${.OBJDIR}/boot strip -s -R .comment -K cngetc ${.OBJDIR}/boot dd if=${.OBJDIR}/boot of=${MOUNT_POINT}/boot bs=512 dd if=bsd.gz of=${MOUNT_POINT}/bsd bs=512 /usr/mdec/installboot -v ${MOUNT_POINT}/boot \ ${DESTDIR}/usr/mdec/biosboot ${VND_CRDEV} @echo "" @df -i ${MOUNT_POINT} @echo "" umount ${MOUNT_POINT} vnconfig -u ${VND} cp ${REALIMAGE} ${FS} rm ${REALIMAGE} DISKTYPE?= rdroot NBLKS?= 3800 # minfree, opt, b/i trks, sects, cpg NEWFSARGS= -m 0 -o space -c 16 -i 4096 bsd.gz: bsd.rd cp bsd.rd bsd.strip strip -s -R .comment -K cngetc bsd.strip gzip -c9 bsd.strip > bsd.gz bsd.rd: ${IMAGE} bsd rdsetroot cp bsd bsd.rd ${.OBJDIR}/rdsetroot bsd.rd < ${IMAGE} bsd: cd ${.CURDIR}/../../../sys/arch/i386/conf && config ${RAMDISK} cd ${.CURDIR}/../../../sys/arch/i386/compile/${RAMDISK} && \ make clean && make depend && COPTS=-Os make cp ${.CURDIR}/../../../sys/arch/i386/compile/${RAMDISK}/bsd bsd ${IMAGE}: ${CBIN} rd_setup do_files rd_teardown rd_setup: ${CBIN} dd if=/dev/zero of=${REALIMAGE} bs=512 count=${NBLKS} vnconfig -v -c ${VND} ${REALIMAGE} disklabel -w -r ${VND} ${DISKTYPE} newfs ${NEWFSARGS} ${VND_RDEV} fsck ${VND_RDEV} mount ${VND_DEV} ${MOUNT_POINT} rd_teardown: @df -i ${MOUNT_POINT} -umount ${MOUNT_POINT} -vnconfig -u ${VND} cp ${REALIMAGE} ${IMAGE} rm ${REALIMAGE} rdsetroot: ${TOP}/../common/elfrdsetroot.c ${HOSTCC} -DDEBUG -o rdsetroot ${TOP}/../common/elfrdsetroot.c unconfig: -umount -f ${MOUNT_POINT} -vnconfig -u ${VND} .PRECIOUS: ${IMAGE} install: .ifndef NOBSDRD cp bsd.rd ${DESTDIR}/snapshot/bsd.rd .endif cp ${FS} ${DESTDIR}/snapshot/${FS} ${CBIN}.mk ${CBIN}.cache ${CBIN}.c: ${CRUNCHCONF} crunchgen -E -D ${BSDSRCDIR} -L ${DESTDIR}/usr/lib \ -c ${CBIN}.c -e ${CBIN} -m ${CBIN}.mk ${CRUNCHCONF} ${CBIN}: ${CBIN}.mk ${CBIN}.cache ${CBIN}.c make -f ${CBIN}.mk all strip -R .comment ${CBIN} ${CRUNCHCONF}: ${LISTS} awk -f ${UTILS}/makeconf.awk CBIN=${CBIN} ${LISTS} > ${CRUNCHCONF} do_files: mtree -def ${MTREE} -p ${MOUNT_POINT}/ -u TOPDIR=${TOP} CURDIR=${.CURDIR} OBJDIR=${.OBJDIR} \ REV=${REV} TARGDIR=${MOUNT_POINT} UTILS=${UTILS} \ sh ${UTILS}/runlist.sh ${LISTS} rm ${MOUNT_POINT}/${CBIN} clean cleandir: /bin/rm -f core ${IMAGE} ${CBIN} ${CBIN}.mk ${CBIN}*.cache \ *.o *.lo *.c bsd bsd.rd bsd.gz bsd.strip floppy*.fs \ rdsetroot boot ${CRUNCHCONF} ${FS} .include <bsd.obj.mk> .include <bsd.subdir.mk> ######################### Any ideas? I'm well aware that there might be better ways to create a live CD but I'd like to play with the instructions from Kevin Lo if it's at all possible. thanks a bunch, Tobias W.
