In the previous article, we have discussed about kiwi imaging system and preparing kiwi as our tools for building openSUSE based distro. Now, we will try another interesting guide, how to make our first openSUSE minimal system liveCD.

Why I choose openSUSE minimal system and not another result, e.g. : openSUSE server or openSUSE desktop liveCD or openSUSE liveDVD, or even openSUSE LiveUSB ? The answer is because the tutorial is the easiest choice ! We can build openSUSE minimal system with a simple configuration, without complicated schema, and get the result within few minutes. Let’s try this :

1. (Optional) Preparing Local Repositories. We could used online repos if we have fast internet connection but I would like to recommended  local repos for our testing. Create local repositories by making a new folder and copying all of DVD contents (or mounted iso image) into the folder. I will used /home/vavai/suse11 as my based source on the following article. Adjust this with yours.
2. Add configuration sample

zypper in kiwi-desc-misc

3. Open /usr/share/kiwi/image/ctso-minimal-suse-11.0/config.xml
4. Replace the repositories address below with your specified repositories or used online repositories for updated software

   <repository type="yast2">
   <!--<source path="/mounts/machcd2/consistent/full-i386"/>-->
   <source path="/image/CDs/full-i386"/>
   </repository>

   e.g. :

   <repository type="yast2">
   <!--<source path="/mounts/machcd2/consistent/full-i386"/>-->
   <source path="/home/vavai/suse11"/>
   </repository>

5. Run kiwi command for processing the first stage (creates a so called physical extend according to the provided image description)

   kiwi --prepare /usr/share/kiwi/image/ctso-minimal-suse-11.0/ --root /tmp/mykiwi --logfile terminal

   The command should be ended with “Kiwi exited successfully done”
   Oct-16 11:19:47 <1> : Umounting path: /tmp/mykiwi/dev
   Oct-16 11:19:47 <1> : EXEC [umount "/tmp/mykiwi/dev" 2>&1]
   Oct-16 11:19:47 <1> : Umounting path: /tmp/mykiwi/proc
   Oct-16 11:19:47 <1> : EXEC [umount "/tmp/mykiwi/proc" 2>&1]
   Oct-16 11:19:47 <1> : KIWI exited successfully   done

6. Run kiwi command for processing the second stage (creates an operating system image from a physical extend. The result of the second stage is called a logical extend or short an image)

   kiwi --type iso --create /tmp/mykiwi/ -d /tmp/mykiwi-image --logfile terminal

   If you found an error like :
   Oct-16 11:24:55 <3> : Couldn’t create squashfs filesystem   failed
   Oct-16 11:24:55 <3> :
   Oct-16 11:24:55 <1> : EXEC [rm -rf /tmp/mykiwi-image/mykiwi-read-write]
   Oct-16 11:24:55 <1> : EXEC [rm -rf /tmp/mykiwi-image/mykiwi]
   Oct-16 11:24:58 <3> : KIWI exited with error(s)   done
   Then, install squashfs from the repositories (zypper in squashfs from konsole)
   Kiwi must be ended with “KIWI exited successfully done”. If you got an error, please take care and resolve the problem because you will not get the iso

7. Goto /tmp/mykiwi-image and find ctso-minimal-suse-11.0.i686-1.1.2.iso file. It’s an iso image. You could burn the iso image into CD or used the iso image as dvd rom source with your virtualbox or vmware.

Good luck, you has been successfully building your first openSUSE based distro, but please wait. This step is not completed either

Try to run the iso image. It will get you a standard and nice openSUSE boot process and ended with the user login on console. It’s normal because openSUSE minimal system used text mode only and run on init 3 by default. The abnormal situation is that we could get into the system with any user name !

To add the default root user with blank password and standard Linux user, follow this instruction :

1. Edit the /usr/share/kiwi/image/ctso-minimal-suse-11.0/config.sh file and add following code after baseCleanMount and before exit 0

   #======================================
   # /etc/sudoers hack to fix #297695
   # (Installation Live CD: no need to ask for password of root)
   #--------------------------------------
   sed -i -e "s/ALL ALL=(ALL) ALL/ALL ALL=(ALL) NOPASSWD: ALL/" /etc/sudoers
   chmod 0440 /etc/sudoers
   
   /usr/sbin/useradd -m -u 999 linux -c "Live-CD User" -p ""
   
   # delete passwords
   passwd -d root
   passwd -d linux
   # empty password is ok
   pam-config -a --nullok

2. Remove existing physical extend

rm -rf /tmp/mykiwi

3. Rebuild your iso by run the command on first stage and second stage :

   kiwi --prepare /usr/share/kiwi/image/ctso-minimal-suse-11.0/ --root /tmp/mykiwi --logfile terminal
   kiwi --type iso --create /tmp/mykiwi/ -d /tmp/mykiwi-image --logfile terminal

The tutorial above is quite simple, but we could extend the result by adding another application into config.xml schema. KIWI is smart enough to add the application and their dependencies, so don’t be afraid with the installation process for every application. KIWI also smart enough for finding relevant repositories if we providing multiple repos.

If you wish to add desktop environment, GUI application or another 3rd party application, ad the package within <package name=”name-of-package”/>. It may be too complicated for adding every package into the config.xml schema but we can avoid these by using KIWI features : pattern usability.

We will learn more about using KIWI and Pattern for “Building openSUSE 11.0 KDE 3.5 LiveCD” on next article.

In this meeting I will act as host and at the same time will hold a presentation, a workshop materials entitled : “Remastering openSUSE: How to Build your Own openSUSE.” openSUSE Remastering will be using kiwi imaging system that is easy to used to build the openSUSE based distributions with our specifications. For example, if we only want to make special openSUSE based distro which fully support and act as server without a GUI and desktop applications, we can create this by Kiwi imaging system. We can also make openSUSE LiveCD or LiveDVDs with our own content, ie : the distro is accompanied by a complete multimedia package Support, wifi drivers, Nvidia & ATI drivers, etc.

In contrast with previous meetings, this meeting was held on Sunday at 10 am(ussualy hold on Saturday 01 pm) because I haveJapanese language course in the office. In addition to the reason for that, this time the event will also discuss plans for Indonesian openSUSE community for next year.

For colleagues who are interested in coming, please read the details on the website of Indonesia openSUSE community. If you need number of contacts that can be contacted, please send an email to the address at vavai vavai.com.

See you in the meeting.
