Problems with running remastered Knoppix :(

[piom]

We have problem with compressed KNOPIX file, when we copy its content as
it is in manual written at http://gnubox.dyndns.org:8080/~sunil/knoppix.php
and we do not even remaster it but only compress it
back, the file size is bigger than the original one.
Than we are starting to boot the new prepared Knoppix, and here is the
problem. During the start procedure, when Knoppix should start to
accessing the compressed KNOPPIX file it writes:
"
Welcom on KNOPPIX live CD:

Accessing KNOPPIX CDROM at /dev/scd0 ... /modules/cloop.o:init_module:
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters

Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.
Press rest button to quit.
"
So it hangs.
It seems like,the booting image could't find, the directory with kernel
in compressed KNOPPIX file.
Do I have to remaster the boot.img, or why is that problem.
This happend also when we place that file KNOPPIX from another version
of Knoppix.


Do You know why it is?
Thanks anyway for answer.

Not sure if this is the trouble or not but if you're trying to boot the compressed image from hdd then it expects to find the compressed file system KNOPPIX in a folder also named KNOPPIX. So it is:

/KNOPPIX/KNOPPIX

As long as it's the first /KNOPPIX/KNOPPIX found it should boot it ok.

No You don't understand me.
I dekompress the file KNOPPIX from cd to remaster it, but I don't remaster it.
I just comprest it back by mkisofs -R source | create_compressed_fs - 65536 source, or somethig like that, so that I get bak the compressed KNOPPIX file.
Than I make CD with structure like this:
/
KNOPPIX
|
+KNOPPIX (rekompressed file)
+boot.img (from the original KNOPPIX CD)
+boot.cat (from the original KNOPPIX CD)
and boot.img was also given as booting image (e.g. in K3B)

And that CD could not run
If I do it exacly the like that with KNOPPIX file from oryginal Knoppix CD it works.
So it looks like minilinux from boot.img could not get to prepared by me KNOPPIX file.

I have done that remastering on 4GB partition with ext2 file system, I have tried to remaster latest Knoppix v3.3 from 2 XI 2003. I don't know if it is needed but I haven't done any cleanup procedures (because I do not change nothing).
I have just decompressed it and compressed it. Befor I have been trying remaster the CD but the result was the same.

Has anywone idea why, the new "remastered" CD can't work?
Thanks for answers.

I'm not sure if it matters but I thought I read that the ext3 filesystem was used or should be used in remastering. You said the file was larger when you did it. Does that mean it didn't all fit on the CD? My 700MB CDROMs are pretty much 100% full with the standard Knoppix image.

Another thing about remastering is that Klaus uses a script to organize/order the files put in the KNOPPIX/KNOPPIX image for quicker boot time loading. But that shouldn't prevent your booting.

[piom]

What kind of script is used for reorganization files by Knopper.
Where can I find it.
Why is ext3 used, can I use reiserfs?

Waiting for response.

Now, everything is working, we try again with the prosedure from page I mentioned above(first news). Remember to download knoppix.clean script from that page.
Hardware infos:
1GB swapfile + 256 MB RAM
4,8GB ext2 partition for manipulation
it takes 40min. on P4M 1.7GHz
Compressed file KNOPPIX in directory KNOPPIX was burned by Nero under Windows and boot.img was given as booting image.
KNOPPIX file was created under Knoppix running from CD by
mkisofs -R source_dir | create_compressed_fs - 65536 > dest_dir/KNOPPIX.

I had difficulties when I used an installed 3.2 to compress for a 3.3 CD. the cloop.o and create_compressed_fs changed to 64 bit from 32 bit or some such. The cloop.o in the boot.img from the new CD is 64 bit and your created_..._fs was 32 bit.
