Remastering 3.4 - ISOLINUX booting problem, image not found
Hi folks, I'll try to be as brief as possible and hope this thread consolidates the issues on booting process for 3.4 remastering.
Here is the setup (following the howto convention) I've hd-installed 3.4 and doing the remastering on the hd
Source tree:
mkdir /mnt/sdb2/knx/source
mkdir /mnt/sdb2/knx/source/KNOPPIX
cp -pR /cdrom/boot /mnt/sdb2/knx/source/
since booted from the hd, the cdrom does not contain the rootfs. Copy the compressed file to disk
cp /cdrom/KNOPPIX/KNOPPIX /mnt/sdb2/knx
Create a folder to mount
mkdir /mnt/sdb2/compressed
Load cloop and mount the compressed FS
insmod cloop file=/mnt/sdb2/knx/KNOPPIX
mount -o ro /dev/cloop /mnt/sdb2/knx/compressed/
Copy everything from compressed fs to source tree under KNOPPIX
cp -pR /compressed/ /mnt/sdb2/knx/source/KNOPPIX/
Now chroot to /mnt/sdb2/knx/source/KNOPPIX
if /dev/null errors occur, go edit fstab and add suid to mount options for /mnt/sdb2/ (in my case) This is covered in the Howto.
RootFS coppied unmount it.
umount /mnt/sdb2/knx/compressed.
rmmod cloop.
Now we have
/mnt/sdb2/knx/source/boot
/mnt/sdb2/knx/source/boot/isolinux/ (and files there)
/mnt/sdb2/knx/source/KNOPPIX/ (the root file system with /boot, /etc, /usr... etc etc)
Create a placeholder for remastered cd
mkdir /mnt/sdb2/knx/master
copy boot from cdrom
cp -pR /cdrom/boot /mnt/sdb2/knx/master/
create KNOPPIX root
mkdir /mnt/sdb2/knx/master/KNOPPIX
and with mc copy everything from /cdrom/KNOPPIX/ to /mnt/sdb2/knx/master/KNOPPIX/ except that ~700MB KNOPPIX file.
Assuming that we have done remastering installed and uninstalled programs in the chroot of /mnt/sdb2/knx/source/KNOPPIX which I did not do to see if everything will be ok at the first place so I did not touch anything yet.
We now have to create the compressed file KNOPPIX from source to master. (right?)
The command for that is
mkisofs -R -U -V "KNOPPIX.net filesystem" -P "KNOPPIX www.knoppix.net" -hide-rr-moved -cache-inodes -no-bak -pad /mnt/sdb2/knx/source/KNOPPIX | nice -5 /usr/bin/create_compressed_fs - 65536 >/mnt/sdb2/knx/master/KNOPPIX/KNOPPIX
Go and verify you have the large file in /mnt/sdb2/knx/master/KNOPPIX/KNOPPIX
Now we will create the CD iso. with boot sector.
cd /mnt/sdb2/knx/master/
mkisofs -pad -l -r -J -v -V "KNOPPIX" -no-emul-boot -boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -o /mnt/sdb2/knx/knoppix.iso /mnt/sdb2/knx/master
After a while we'll end up with knoppix.iso in /mnt/sdb2/knx/
Burn it and boot with it.
Here comes the problem. After booting The screen says
ISOLNUX 2.04 (Debian, ...date..) (version info and author...)
Could not find kernel image: linux
boot:
Any thoughts?
I didn't touch the miniroots under /boot/isolinux namely minirt24.gz and minirt26.gz Which I would like to customize too. But I could not create a bootable cd at the fisrt place.
Is there anything I'm missing.
Any help is appreciated.
Cheers.

I've successfully created a bootable remastering from 3.4; I've followed the instructions you can find at http://www.knoppix.net/docs/index.ph...masteringHowto
The only difference I can see is that I've booted from CD instead of installing it to HD and doing the work from there. Sorry not to have an idea about your problem

hi..
hi..
i found a answer...
isolinux giving message : "could not find kernel image: linux"
because isolinux cant find right config file and image file and trying to open default image file "linux".

my config and image files looking after making iso like this:
isoconfig.cfg -> ysoconfyg.cfg
