5.3.1 heavily remastered + 18 kernels (2.6.12-28)

Hi peoples. I'm pretty close to finishing a 5.3.1 heavily remastered featuring 17 extra kernels besides the original 2.6.24.4. HAL working OK, all kernels working with aufs and cloop and ALSA 1.0.17 (hm, ALSA except 2.6.14 :( ), lots of packages added, lots of -dev packages also added, looks better anyway. Electronics stuff added, like some 8 different gEDA versions (compiled) and Xcircuit and lots of others, also Firefox 2 and 3, VLC 0.9.8 (compiled), peazip and p7zip, mplayer compiled and more.

In this thread I created I intend to put everything I know and experimented: how to remaster a 5.3.1 starting from the original ISO, details about new kernel compilation, details and tricks about the scripts in knoppix (5.3.1) and where to change things if you want to make things work etc. etc. etc.

My personal approach to remastering (at least for now) is to make it a direct competitor and efficient replacement of Windblows. So I will focus especially on a remaster with all the X features required for an easy to use graphical operating system.

As I go on, I will probably edit this first post here and insert some table of contents, which will take you directly to what you're looking for

Also I think it would be best if nobody else would post here, not for a while anyway, until I get the whole thing started properly. Well, of course this is at your choice, it's not a request but rather a preference.

I'm starting with kernels, by giving example scripts and scripts that you can test directly under the Live Knoppix 5.3.1 DVD running on a machine with enough RAM for experimenting directly on the ramdisk.

Ok, I'm back after a busy while, and this time I'm going to describe a few things I managed to do while tailoring knoppix to my preferences.

I see there are people asking around about ways to compile / upgrade the kernel, so I'm going to write here everything I've done while adding new kernels to knoppix 5.3.1.

First, I will describe in simple steps how can you compile a (new) kernel in the knoppix environment

Compared to the general way of kernel compilation in Linux, doing this in knoppix is somewhat simplified, in that you don't have to do "make bzImage" and "make modules" anymore.
Suppose we want to add kernel 2.6.12 to the existing 2.6.24.4 in Knoppix 5.3.1.

Well, to do that, I used this particular script, ran under the original Knoppix 5.3.1 environment, in a chroot under a directory where I put the entire knoppix filesystem, uncompressed.
All my remastering takes place under the original Knoppix 5.3.1 environment, that is under X.
So, to be more clear: under the original Knoppix 5.3.1 environment, I mount the original knoppix ISO stored somewhere on my harddrive, I then mount those two big files KNOPPIX and KNOPPIX2 as cloop devices, and I copy their contents to a directory on a partition of my harddrive (let's say /mnt/hda2/KNOPPIX), then I open another konsole window where I chroot to the freshly copied filesystem (chroot /mnt/hda2/KNOPPIX), from there I mount the partition containing my remastering kit (remastering scripts + additional data files used, let's say /dev/hda4), I then change dir to the remastering kit and then I run this script:

depmod -a 2.6.12

---

Now I will explain every line of this script:

Code:

---

odir=`pwd`

---

This creates a variable named "odir" containing the current directory at the beginning. This directory contains (along with this script) others subdirectories where I keep files used by this script. The directories used in this particular script are:

kernels/ ___________this contains the kernels configurations for all new kernels, which configurations I created manually for each kernel.
kernels/kernel.org/ ___this contains the kernels downloaded from kernel.org, as tar.bz2 archives
hardware/ _________this contains drivers for various hardware I have, including ALSA drivers archives downloaded from the ALSA site
dvd/ ______________this contains the exact file structure of the original Knoppix 5.3.1 DVD, EXCEPT FOR the compressed filesystem (that is files KNOPPIX/KNOPPIX and KNOPPIX/KNOPPIX2)

Next:

Code:

---

cd /usr/bin
rm -f gcc
rm -f g++
ln -s gcc-3.3 gcc
ln -s g++-3.3 g++

---

What this does is it changes the symbolic link "gcc" in /usr/bin to point to the gcc version 3.3.

Why? Because the kernel evolved in time, and so did the C compiler. Older kernels are supposed to be compiled with some C compiler of the same age, that is older compilers, or at least that's my approach. For my remaster I used gcc 3.3 to compile kernels 2.6.12 to 2.6.19, and gcc 4.0 to compile kernels 2.6.20 to 2.6.28. Don't ask how I came to this conclusion, I just felt like I needed to do it this way. That does not mean you are not free to use whatever compiler you wish. Only one thing I want to make clear here: When you compile a kernel, you have to use the same compiler to compile extra modules for it. For instance, if you compile kernel 2.6.12 with gcc-3.3, and you also want to compile (some newer) ALSA drivers for this kernel, you have to use the same gcc-3.3 for ALSA

Next:

Code:

---

[ -d /lib/modules/2.6.12 ] && echo -en "\n\n---------------------------------------------------------------\nremoving /lib/modules/2.6.12 ..." && rm -rf /lib/modules/2.6.12 && echo "done."

---

What this does is, in case I run this script twice or more times, it deletes 2.6.12 kernel files left from previous compilation attempts. This is not really necessary when I have everything working OK, after the script is thoroughly tested and proved to do exactly what it supposed to. But since I used this code in the beginning, I just left it here uncommented.
So, the files that have to be deleted are: the directory /lib/modules/2.6.12 containing kernel modules, the directory /usr/src/linux-2.6.12 containing the kernel sources (unpacked from the tar.bz2 downloaded from kernel.org), the directory /usr/share/doc/linux-image-2.6.12 (part of the installed kernel 2.6.12), the directory /usr/src/modules/atl1-2.6.12 (this is where I unpack the driver source for my particular network interface, which is not contained in the kernel since the kernel is much older than the hardware), the directory /usr/src/modules/aufs-2.6.12 which contains the sources for the aufs module used with this particular kernel, and the directory /usr/src/modules/cloop-2.6.12 which contains the sources for the cloop module used with this particular kernel.

[ -f $odir/kernels/.config-2.6.12 ] && cp -fpv $odir/kernels/.config-2.6.12 .config

---

Here, I change dir to /usr/src, I extract the kernel sources for 2.6.12 from $odir/kernels/kernel.org/linux-2.6.12.tar.bz2, thus creating a new subdirectory named "2.6.12" under "/usr/src" and then I change the symbolic link "linux" found in "/usr/src", so that it points to "2.6.12".

#----------------------------------------------------------------#
For those who don't know yet, /usr/src/linux is always a link pointing to the current kernel sources, in this case 2.6.12.
Why?, because it's a general rule expected to be true by many other programs, so I keep it true.

Another thing is, you probably notice that instead of simply commenting my actions in the script, I actually print them on the console with "echo". That shoots two birds with one bullet: I see the comment when I read and check my script, and I also see the comment in the compilation log left in the konsole window.
#-----------------------------------------------------------------#

Then I cd into the freshly unpacked kernel sources. Here, I copy the kernel configuration file. If I do not already have a custom configuration file that suits my preferences, I start from the kernel configuration copied from Knoppix 4.0.2, which happens to use the same kernel, 2.6.12. It's a starting point anyway better than kernel 2.6.24.4 which comes with knoppix 5.3.1.

#-----------------------------------------------------------------#
As a comment, I will say here that when you unpack a kernel and start configuring it (with "make menuconfig" for instance) the configuration script will try and find a default kernel configuration file in the system. If it doesn't find a file named ".config" in the root of the kernel source being compiled, it will look for one in the directory "/boot". This directory contains the configuration file for the kernel currently running, which in our case is 2.6.24.4.
Now this kernel being much newer than 2.6.12, when the configuration script (for 2.6.12) tries to import the configuration (for 2.6.24.4) it will complain about attempts to import unknown variables, which is normal, since newer kernels have more and newer config variables (newer drivers, newer features etc.). Also it is possible that some of the config variables for 2.6.12 do not exist anymore in 2.6.24.4, so they will not be imported in 2.6.12, which means more manual work to do for 2.6.12 at configuration time.

Anyway, the idea is I'm using the config from knoppix 4.0.2 as a starting point for my 2.6.12 kernel.
I do "make menuconfig", I go through all menus checking what I want in my 2.6.12 kernel and what not, then I save this configuration, then I start compiling the kernel. I watch the whole process and check for error messages for different drivers/features. If I see some error while compiling a particular driver in the kernel, I start configuring 2.6.12 again, making sure I disable that pesky driver. And so on, until I get a compilation log as clean as possible. When I'm satisfied with my compilation log, I save that kernel configuration as ".config-2.6.12" in the $odir/kernels/ directory I previously mentioned
#-----------------------------------------------------------------#

So, if I already have the final config file for my 2.6.12 kernel (in other words, the file $odir/kernels/.config-2.6.12 exists), then I copy this file to my 2.6.12 source tree.
If I don't have a final configuration according to my preferences (in other words, the file $odir/kernels/.config-2.6.12 does not exist) then I copy the file $odir/kernels/.config-k4.0.2 to my 2.6.12 source tree. Notice that the file is being copied as ".config" in both cases.

This section of the script takes care of the required kernel patching in order for the aufs module to actually get compiled and work with kernel 2.6.12.

After each patch I put in a comment the kernel versions that require that patch. For instance the "deny_write_access.patch" is only required for kernels starting with 2.6.17

So since for this particular kernel (2.6.12) no patch is required, I just commented out all patches. The only patch I use is the kernel log level patch aka the knoppix kernel patch, which changes the kernel log level from 4 to 1, and I actually do this patch using the "sed" command instead of patching with a "patch" command.

#-----------------------------------------------------------------#
NOTE: you probably noticed that this section is in the wrong place. It should be AFTER the aufs source code is unpacked. What happened is that I moved the code that unpacks the aufs source towards the end of the script, because no patch is actually required anyway and I wanted to have all the code pertaining to aufs in one single place.
Historically speaking, I started experimenting with kernels from 2.6.20 downwards until I got to 2.6.12.
#-----------------------------------------------------------------#

Next:

Code:

---

echo "------------------------ make menuconfig -------------------------------"
[ -f $odir/kernels/.config-2.6.12 ] || make menuconfig
cd ..
make kernel
#dpkg -i linux-image-2.6.12_2.6.12-10.00.Custom_i386.deb
dpkg-deb -x linux-image-2.6.12_2.6.12-10.00.Custom_i386.deb /

---

OK, so what happens here is that IF I already have the final 2.6.12 kernel configuration file ($odir/kernels/.config-2.6.12), I DO NOT RUN "make menuconfig" anymore, because there is no point in doing that. I just proceed with the kernel compilation since I already know the compilation will be successfull and with minimum warnings.
IF I don't already have the final 2.6.12 configuration, that means I'm using the configuration taken from knoppix 4.0.2, so further adjustments are necessary, so I run "make menuconfig".
Next, I'm exiting the kernel source directory (/usr/src/linux, or /usr/src/linux-2.6.12) and go to the parent dir, that is /usr/src
Now comes the nice part: thanks to Mr. Klaus Knopper's great work, the kernel compilation is being done by one single command, "make kernel", ran from the "/usr/src" directory. That's because there is a "Makefile" file in this directory, that takes care of everything including the creation of a debian package with the custom kernel being compiled. You will have this debian package in "/usr/src" afterwards. All you have to do next is to install it.
And what I actually do is, instead of installing the package (with "dpkg -i") I just unpack it (with "dpkg-deb -x") like any regular archive into the root of the chrooted environment. Why? Because the debian package has some postinstall script that tries to do some things after unpacking the kernel, like trying to mess with the LILO setup, which is useless since this is a live CD/DVD and we don't need any LILO.
All I have to do after simply unpacking the kernel is to run "depmod -a 2.6.12" at the end of remastering, to make sure that all kernel modules for 2.6.12 have the correct dependency.

cd atl1-2.6.12/src
sed -i -e "s/^BUILD_KERNEL\=.*$/BUILD_KERNEL=2.6.12/" Makefile
make
cd ../../..

---

Here I compile the network driver for my particular network interface. There's not much to comment here, except that I unpack the driver sources in the "/usr/src/modules" directory, in a separate subdir called "atl1-2.6.12" and before compiling I make a little change in the Makefile. After compiling the driver, I exit back to the "/usr/src" directory

Next:

Code:

---

echo "------------------------- make cloop -----------------------------------"

tar -xzf cloop-2.06.tar.gz
mv -f cloop-2.06 cloop-2.6.12
cd cloop-2.6.12
make KERNEL_DIR=/usr/src/linux
cd ../..

---

Here I cd into "/usr/src/modules", I unpack the cloop module sources, from the file "cloop-2.06.tar.gz" that came with knoppix, into a separate subdirectory called "cloop-2.6.12", within "/usr/src/modules".
Then I compile the module according to the instructions, running "make KERNEL_DIR=/usr/src/linux". Once again I say, "/usr/src/linux" is a symbolic link now pointing to "/usr/src/linux-2.6.12"
After all is done, I exit back to "/usr/src"

Next:

cd aufs-2.6.12
cp $odir/aufs-patch-2.6.11.patch .
patch -p1 <aufs-patch-2.6.11.patch

---

What happens here is that I cd into "/usr/src/modules", I unpack the aufs module sources into a separate directory called "aufs-2.6.12" which I then enter, and there I copy a patch for aufs that makes it work with kernel 2.6.12. Then I apply the patch to the aufs source

Next:

Code:

---

echo "------------------------- make aufs ------------------------------------"
#make KDIR=/lib/modules/2.6.12/build -f local.mk kconfig
make KDIR=/usr/src/linux -f local.mk

---

Here, I just compile the aufs module, according to the instructions, as an external module, using the command "make KDIR=/usr/src/linux -f local.mk". The command before it that I commented out is used when you wish to have the module embedded into the kernel, which I'm not interested in, so you just ignore that line.

depmod -a 2.6.12

OK, we're finally at the end of the script. What happens here is this: I create a separate directory for my network module (/lib/modules/2.6.12/kernel/drivers/net/atl1) where I copy the module I previously compiled. The module name is atl1.ko. I also copy this module to my remastering package in case I need it later. Then I also copy the aufs and cloop modules to my remastering package. The aufs and cloop modules are used as external modules, they are loaded when knoppix is booted, from the linuxrc script. On the original Knoppix DVD these two modules are placed in the "KNOPPIX/modules" directory. What I did is, I kept the original modules that came with Knoppix and I created separate subdirectories "2.6.12", "2.6.13", "2.6.14", ..... "2.6.28" for my extra kernels, inside this "KNOPPIX/modules" directory on the DVD. In these directories I then copied the cloop and aufs modules I use for my extra kernels.

OK folks, there's more to this episode ("The 2.6.12 episode"), but I have to take a break here, it's almost one hour after midnight and I have to kinda go to bed or something. But I'll be back soon with the rest of this episode. Thank God it's been Friday night, otherwise I wouldn't have so much time to write all this

OK, I'm back, and as I write I'm testing a script I assembled from my actual separate scripts I use for remastering.

What this script does is it downloads a proper version of aufs from the repository, it also downloads the 2.6.12 kernel from kernel.org and then starts compiling the kernel along with the aufs and cloop modules and after that it creates a minirt.gz for use with this kernel (and KNOPPIX 5.3.1 of course).

This has just an instructional/educational purpose, at least for now, because even with the kernel compiled along with the modules, we still have to install the kernel in the KNOPPIX filesystem. That means the compressed filesystem has to be unpacked, chrooted into and the 2.6.12 kernel installed in it.

But whatever, I just want to show a script that does all the kernel stuff starting from as little as possible, using 2.6.12 as an example.

REQUIREMENTS:

- A computer with 2GB RAM
- The KNOPPIX 5.3.1 DVD
- The "2.6.12-knoppix-kernel-compiler-installer" script
- The ".config-2.6.12" file (kernel configuration for 2.6.12)
- The "aufs-patch-2.6.11.patch" file (aufs patch to make it work with 2.6.12 kernel)
- The "linuxrc" file (a script which is included in minirt.gz; this is modified by me in a few places)

So basically what you need is my script and three additional files. I posted all these four below as code.
You just have to save these four code sections with the names indicated above, make the "2.6.12-knoppix-kernel-compiler-installer" script executable and run it.
That's it.

=== EXTREMELY IMPORTANT !!!!!! ===
You will have to use your mouse and copy the code posted below. When doing this, please enlarge your web browser's window as much as possible until you see NO LINE in the script reaching the right margin of the window code. If you don't do that, some lines in the script being very long, they will be split on two rows and the code will not work.
You might want to use Iceweasel as browser for this (comes with Knoppix 5.3.1) and use the "Ctrl -" key combination (that is CTRL and the "minus" key on the numeric keypad) to make the fonts smaller so all the lines can fit your screen in one piece.
Scroll up and down and make sure you see NO LINE in the code reaching the right margin. After that, position your mouse cursor at the beginning of the code and keeping the left button pressed drag down until you select all the code. Then press Ctrl-C.
================================

Now, for those really unfamiliar with Linux in general, I will give some detailed instructions:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
What you have to do:
==================
- Start your computer with KNOPPIX 5.3.1 DVD
- Open a konsole window (it's on the taskbar on the left)
- Change the font for the konsole (from the menu, Settings -> Font -> Shrink Font, a few times until the font gets smaller)
- Change to root (type "su" and Enter)
- Run mc (Midnight Commander)
- From mc, create in /home/knoppix a directory with whatever name you want, let's say "kernel-test"
- cd into the directory you just created
- Press the "Shift+F4" key combination (this will start editing a new file)
- Press F9, the menu will show up, go to Options -> General and make sure the option for "Return Does Autoindent" is NOT CHECKED
- Click, drag, select and copy (Ctrl+C) the first code in this post as instructed previously.
- Go back to the konsole window in mc and press "Shift+Insert". This will paste the code in mc.
- Press F2 to save the code and give it the name "2.6.12-knoppix-kernel-compiler-installer"
- Make this script executable: type "chmod 755 2.6.12-knoppix-kernel-compiler-installer" at the command prompt in mc and then Enter
- Click, drag, select and copy (Ctrl+C) the second code in this post as instructed previously.
- Go back to the konsole window in mc and press "Shift+F4" again
- Press "Shift+Insert". This will paste the code in mc.
- Press F2 to save the code and give it the name ".config-2.6.12" (PAY ATTENTION, THE NAME STARTS WITH A DOT ".")
- Click, drag, select and copy (Ctrl+C) the third code in this post as instructed previously.
- Go back to the konsole window in mc and press "Shift+F4" again
- Press "Shift+Insert". This will paste the code in mc.
- Press F2 to save the code and give it the name "aufs-patch-2.6.11.patch"
- Click, drag, select and copy (Ctrl+C) the fourth code in this post as instructed previously.
- Go back to the konsole window in mc and press "Shift+F4" again
- Press "Shift+Insert". This will paste the code in mc.
- Press F2 to save the code and give it the name "linuxrc"
- Got to the konsole window menu, Settings -> History and set History to Unlimited. This way you will have the full log at the end to look through it if you want.
- Make sure these four files are in the same directory (the one you created, i.e. "kernel-test") and then just press Enter from mc on the script (2.6.12-knoppix-kernel-compiler-installer)
- Now relax and wait for it to finish
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

When all is done, you will notice some changes in the directory where you saved the files in the beginning.

A few new files appeared:

- "dvd/boot/isolinux/minirt-2.6.12.gz" and "dvd/boot/isolinux/vmlinuz-2.6.12" should be placed on the DVD, in the "dvd/boot/isolinux/" directory
- the "dvd/KNOPPIX/modules/2.6.12" directory should be copied on the DVD in the "dvd/KNOPPIX/modules/"
- the "kernels/linux-image-2.6.12_2.6.12-10.00.Custom_i386.deb" file is a debian package containing the 2.6.12 kernel. This should be installed in the KNOPPIX filesystem. That means uncompressing the filesystem somewhere on the harddrive, chrooting into it, and installing the package with "dpkg -i linux-image-2.6.12_2.6.12-10.00.Custom_i386.deb"
- the "kernels/loop-aes-modules-2.6.12_3.2b-5_i386.deb" is a debian package containing the loop-aes module. Should be installed the same way as the kernel package.
- For everything to work, there should be a few lines added to the "isolinux.cfg" on the dvd:

Code:

---

LABEL linux-2.6.12
KERNEL vmlinuz-2.6.12
APPEND ramdisk=100000 init=/etc/init lang=us apm=power-off vga=791 initrd=minirt-2.6.12.gz nomce noudev acpi=off dma noeject noprompt quiet BOOT_IMAGE=knoppix
