Knoppix Live-CD remastering

At present time this software is a beta-testing.

Description

This software for CD remastering is include a lot of DEB-packages (elphel-specific and dependenced), files and scripts. All software is compressed to the .tar.bz2 archive (package size is approx. 26 Mb).

There are two scripts for remastering.

First script (make.sh) is general and started by user. Source code: 


# Make a clone from existed knoppix live-cd

echo "Welcome to KNOPPIX-to-ELPHIX remastering program"

part=0

query() {

    echo -n "$1 [$2] " >&2
    read answer
    if [ -z $answer ] ; then answer=$2 ; fi

}

# The work directories specifing

echo "Stage 1. Now you can specify the work directories and other parameters"

if [ part=0 ]
then
query "Please, specify the work partition. For example, hda1" hda1
part=$answer
fi

version=`cat debs/version.txt`

home=/home/knoppix/LiveCD-$version

source0=/dev/$part
dest0=/mnt/$part

echo "Mounting the work partition..."

echo "Done"

echo "Creating the work directories..."

mkdir -p $source/KNOPPIX

echo "Done"

echo "Stage 1 is finished without errors"

# The next step - copying files and directories

echo "Congratulations! The remastering is finished. ELPHIX-$version is ready for burning. You can find the ISO-image of ELPHIX-$version on the $dest0 partition. Good luck!"

The second script (inst-rem.sh) is started by the first script automatically and used for removing/installing DEB-packages. Source code: 


# Sub-script for removing and installing packages

ping -c 5 google.com

dpkg -P `cat /debs/remove-debs`

rm -rf /etc/mozilla-firefox/profile/mimeTypes.rdf

dpkg -i --force-overwrite /debs/depend/*.deb

dpkg -i --force-overwrite /debs/*.deb

cd /etc/X11/Xsession.d
patch < /patches/45xsession.patch

cd /etc/init.d
patch < /patches/knoppix-autoconfig.patch

cd /etc/skel/.kde/share/config
patch < /patches/kdesktoprc.patch

exit

System Requirements

You must have:

1. at least 1 GB of FREE RAM+Swap total (e.g. 256M ram, and 750M swap AVAILABLE)

2. 3 GB free on a Linux filesystem (ext2/3, xfs, etc.) formatted disk partition (you must unmount this partition before remastering)

3. Knoppix 4.0.2-2005-09-23 EN

Instruction

1. Download the LiveCD-1.4.3-beta6.tar.bz2 archive from SourceForge http://prdownloads.sourceforge.net/elphel/LiveCD-1.4.3-beta6.tar.bz2?download

2. Boot from the Knoppix CD

3. Unpack archive to the /home/knoppix directory

4. Open a root shell:

Menu: Kmenu->Knoppix->Root Shell

5. Type the following two commands: 


cd /home/knoppix/LiveCD-1.4.3

sh make.sh

6. The remastering script will be started. You must specify the work partition (for example hda1). This partition will be used for remastering Knoppix.

NOTE: This partition MUST be unmounted!

7. Follow the appeared instructions

8. The ELPHIX-1.4.3.ISO image will be placed at the work partition

9. Use the special software (for example, K3B) for writing image to CD
