Hi

I get an error on unionfs make:

Im using Knoppix5.01 Kernel 2.6.17.8

With other unionfs versions there are other errors, too

Thx for HELP

You don't need to do the full make to upgrade the Knoppix kernel, you only require the unionfs.ko file. This can be compiled using:

# make unionfs.ko

[Linuxgamer]

Thx it works.

In Knoppix 5.01 the modules cloop.ko an unionfs.ko are not in minirt.gz but in knxmaster/KNOPPIX/modules

And modify linuxrc is not necesarry.

btw: Why is in Knoppix Kernelconfig the "Video mode selection support" not available i think i need it for bootsplash. Or not?

I try to follow this howto for bootsplash: http://knoppix.net/forum/viewtopic.p...d57f258d5cf392

I try to copy the pics into miniroot but i get the error:

cp: Schreiben von ,,./silent-1024x768.jpg": Auf dem Gerät ist kein Speicherplatz mehr verfügbar

This means no space is avaliable on minirt.

What can i now do?

Hi

I have recompiled the Kernel 2.6.17 and get the errors on boot:

ACPI: Unable to locate RSDP

PCI: PIIX3 Enabling Passive Release on 0000:00:01.0

Starting udev hot-plug hardware detection ... Failed.

How can i fix this?

Is all this information current for Knoppix 6.0.1? I'm trying to update the knoppix 2.6.28 kernel
and wondering if all of this is still accurate after being a few years since the last post.

[bl8n8r]

Probably not going to get any replies so putting my notes here (for knoppix 6.0.1)
This produced a bootable 6.0.1 knoppix cd with re-compiled 2.6.28.4 source
from kernel.org

The below uses knoppix remastering howto at:
http://www.knoppix.net/wiki/Knoppix_Remastering_Howto

If you want to modify kernel, then in addition to remastering howto...

* grab regular kernel source from kernel.org and unzip in /usr/src
also symlink /usr/src/kernel-xxxx to /usr/src/linux

* cloop and aufs modules are still needed for cdrom booting as well
as knoppix functionality. These need to be compiled against new
kernel source and copied into correct /lib/modules/kernel... and
/mnt/hda1/knx/master/KNOPPIX/modules/ directories.

* it appears the only think /mnt/hda1/knx/master/boot/isolinux/minirt.gz
does now is provide important slash directories as well as the initial
boot script "init".

** There are no modules in minirt.gz anymore **

* after compiling new kernel, copy /usr/src/linux/arch/x86/boot/bzImage
to /mnt/hda1/knx/master/boot/isolinux/linux. This is the kernel the
cdrom uses to boot. Forget about grub and the /boot directory.

* be sure you compile cloop.ko and aufs.ko modules and put them under
/lib/modules/kernel-version/ somewhwere. They also need to be
added to /lib/modules/kernel-version/modules.dep somehow. If you
are compiling under a different kernel and chrooted in your knoppix
tree, this could be difficult. (Maybe export KDIR?). In a pinch,
I just edited modules.dep and added the lines by hand (depmod complained
otherwise)

* I never did anything with unionfs.ko - so it must be deprecated??
aufs.ko and cloop.ko are all that seem to be needed for booting.

This is what I did on my debian workstation
after following knoppix remaster howto
----------------------------------------------
# aptitude install zlib-devel
# cd /usr/src/
# wget http://debian-knoppix.alioth.debian....2.628-2.tar.gz

make hurled here...
google found this:

Hello all,

Attempting to update kernel on my knoppix 5.3.1 re-master project to 2.6.30.5 and found this thread.
I realise this is mainly a thread from 2005/2006 but with recent additional input. Hoping that people are still interested...

I have a problem concerning unionfs. Due to updates the structure of the unionfs snapshot differs from the tutor and I am hoping for help on how to proceed.

ftp://ftp.fsl.cs.sunysb.edu/pub/unionfs/snapshots/ exists ok and two files are listed:

05/24/08 12:00AM        19,000,994 unionfs-cvssnap.tar.gz
10/22/07 12:00AM        112,696 unionfs-utils-0.3pre-cvs200710212004.tar.gz

I have download and expanded both. unionfs-cvssnap.tar.gz expands to three directories

CVSROOT
unionfs
unionfs-utils

Under unionfs, there is a Makefile.v file and under unionfs/Attic, there is a fistdev.mk,v

I have also been looking here:
ftp://ftp.filesystems.or/pub/unionfs
It has the same + additional info but still stuck.
How can I compile a unionfs from these files?

Lastly, could anyone explain how to tie up the version of both unionfs and cloop with the kernel version?
For example, if exists a 1 to 1 match may this part of the process be simplified? I am thinking of updating my kernel to 2.6.28.4, thus matching knoppix v6 and merely taking the unionfs and cloop files from there. (I do have reasons for not just re-mastering v6 instead!)

Regards Steve

Hello

Proceeded as discribed in my first mail, ie compiled new kernel & cloop without any (apparent problems).
Although I installed the debian CSV client was unable to get a conection to:

  cvs -z3 -d:pserver:anonymous@aufs.cvs.sourceforge.net:/cvsroot/aufs co -P aufs

Just got a "connection timed out error"

So I used the aufs.ko from knoppix V6 and made an iso build anyway.
I get this error

Welcome to the KNOPPIX live GNU/Linux on CD!

I compiled cloop as described by bl8n8r:

# tar xvfz cloop_2.628-2.tar.gz 
# cd cloop-2.628 
# make KERNEL_DIR=/usr/src/linux/

It completed without error

Although I am still expecting aufs problems, can anyone help with this cloop error?

Regards,

Steve
