Error customising Knoppix 3.7

[Saint0453]

What I am trying to do is add the mmls program to Knoppix 3.7

I was following the Knoppix customising instructions at:

http://www.knoppix.net/wiki/Knoppix_Remastering_Howto

I removed the Open office package and then copied the mmls file into the knx\source\KNOPPIX\bin directory.

I was at the following step:

Now we'll make the big KNOPPIX file which is a cloop compressed ISO 9660 filesystem : mkisofs -R -U -V "KNOPPIX.net filesystem" -publisher "KNOPPIX www.knoppix.net" -hide-rr-moved -cache-inodes -no-bak -pad /mnt/hda1/knx/source/KNOPPIX | nice -5 /usr/bin/create_compressed_fs - 65536 > /mnt/hda1/knx/master/KNOPPIX/KNOPPIX

I get to:

[ 9] Block # 24577 size 65536 -> 8287 [compression ratio 12% overall 37%]
Killed

Does anyone know why the build is killing itself and stopping (I have tried it twice)? Is there a better meathod to add the mmls function (the file is only ~200 k).

Thanks.

Do you have the required RAM and swap space (1 GB or more)? If yes, had you forgot to enable swap space before starting compression?

Check and reply..

[Saint0453]

No my machine only has 256 MB of RAM. For that reason I input (from the instructions):

cd /mnt/hda1/knx ; dd if=/dev/zero of=swapfile bs=1M count=750 ; mkswap swapfile ; swapon swapfile

I figured that command would give me the swapspace I needed. Do I have to enable that someway?

Thanks.

[raj1478]

No it is fine. It is giving you the required swap space. But I recommend you to have swap of 1GB i.e. change the count=750 to 1000 in the command and retry. I faced similar problem once but the reason was that I hadn't enabled enough swap space.

Tell the results.

[Saint0453]

Thank you so much. That worked, guess didn't have enough swap space.

Thanks again.

Do you know if there is a way to remove the checksum from the knoppix cd? (I have seen numerous post about this but no respose).

Why I ask is because:

I am trying to use Magic ISO (http://www.magiciso.com/) to create a tripple dual boot Helix, DOS and KNOPPIX CD/DVD. So I can boot either Helix or KNOPPIX or Snapback/Ghost in DOS.

When I Setup the dual boot and try to boot to Helix I get the following error: (I assume KNOPPIX would be the same, thus far I have only tried a dual boot CD using DOS and Helix)

"ISOLINUX 2.04 (Debian, 2003-06-06) isolinux:
Image checksum error, sorry..."

All the files from the original ISO image are present on the CD the only thing that has changed is the dual boot option.

Is there a way to remove the checksum that occurs at boot?

Thanks.

(Would it be better for me to start a new topic for this subject?)

Do you know if there is a way to remove the checksum from the knoppix cd? (I have seen numerous post about this but no respose).

All you have to need is to remove the md5sums file from the source of CDROM (I guess you are using original FAQ of remastering then this directory will be "knx/master") and then don't type the command that updates the checksums i.e. rm -f KNOPPIX/md5sums; find ...... something like this. Only give the command starting with "mkisofs" to create the iso.

Tell the progress.

So i went from the step where you make the big KNOPPIX file. then i did:
cd /mnt/hda1/knx/master

I skipped the step:
rm -f KNOPPIX/md5sums; find -type f -not-name md5sums -not -name boot.cat -not -name isolinux.bin -exec md5sum '{}' \; >> KNOPPIX/md5sums

I then went to the step:
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/hda1/knx/knoppix.iso /mnt/hda1/knx/master

At this piont i get the error:
mkisofs: Uh oh, I cant find the boot image 'boot/isolinux.bin' !

Any suggestions on how to include this but not the chucksum?

Thanks.

The command looks OK.

Check if there is a boot directory in the master with isolinux directory.

If yes, have you really given the command "cd /mnt/hda1/knx/master".

Is your remaster really on "hda1" partition or somewhere else...?

Update me...

[Saint0453]

The command looks OK.

I checked and there is a boot directory in the master with a directory isolinux inside of it. Inside of the isolinux direcotry there is a file: isolinux.bin

If yes, have you really given the command "cd /mnt/hda1/knx/master".

I re-entered the command just to be sure and yes I am in the /mnt/hda1/knx/master directory.

Is your remaster really on "hda1" partition or somewhere else...?

Techincally no, my remaster is on hda2 but starting from the begining of the "Remastering Howto" I changed:
mount -rw /dev/hda1 /mnt/hda1 to mount -rw /dev/hda2 /mnt/test

Throughout the instructions anywhere I saw a "hda1" I changed this to a "test" (the mount point for hda2).

Should there not be a boot directory in the /knx/master directory?

Thanks.

[raj1478]

The commands look OK. But the problem with the mkisofs command, which itself is reporting, that it can't find boot file "boot/isolinux.bin". So, the only possibility I can think out is a typing mistake or the file isolinux.bin may be corrupt. Try to replace boot directory with the boot directory of original CD and tell the progresss.
