BabelBox: automated DebianInstaller testing and demo machine
BabelBox is a system designed to demonstrate the automation capabilities of the Debian Installer. It also shows the high number and the quality of translations available for the installer. It is well suited for a live demo on a booth in an expo or any other event.
BabelBox runs a continuous series of fully automated installations in different languages, using both the text-based and graphical frontends of the installer. After each installation the demo system is booted into the newly installed system for a short time.
BabelBox is based on the hd-media installation method and can be run off a single machine, even without networking.
For this setup using a single "clean" hard disk is recommended. A setup using two hard disks is also possible but will need some modifications in the preseed file and scripts.
The original BabelBox setup (see DebianInstaller/BabelBoxOrig) was based on the netboot installation method and requires a separate server besides the actual demo machine.
Setting up the demo machine
The demo machine will be set up for two multi-boot systems:
- a basic Debian installation that controls the demo and contains all files needed to run the demo;
- the second system will be deleted and overwritten for each demo installation.
Installing the controlling system
Perform a basic installation using your preferred installation method. When you get to partitioning, create an ext3 Linux partition on /dev/sda1 (about 1.5 to 4GB depending on which media you want to use as installation media) and a Linux swap partition on /dev/sda2. Continue the installation after that, installing a standard system including grub2.
After you booted into this system, call fdisk again, and add an Extended partition /dev/sda3 (about 2.5 to 3GB should be fine). Add the remaining free disc space to a primary partition /dev/sda4. This partition must exist and be at least one cylinder big.
You should now have something like the following:
Device Boot Start End Blocks Id System /dev/sda1 * 1 486 3903763+ 83 Linux /dev/sda2 487 548 498015 82 Linux swap / Solaris /dev/sda3 549 899 2819629 5 Extended /dev/sda4 900 4998 32925217+ 83 Linux
The idea here is to create a first partition to hold the controlling system and to leave the third (extended) partition free for the demo system. The fourth primary partition is just to fill up the hard disk so that formatting for the demo system will not take unnecessary long. The fourth primary partition must be defined, even if it is only one sector in size.
Setting up the controlling system to run BabelBox
Everything needed to run the demo will be placed in /srv on the controlling system.
Make sure you are in /srv and that you have write access
Download the hd-media images (vmlinuz and initrd.gz) for the graphical installer
Download the tarball with additional files and unpack it using:
# tar xzf babelbox.tgz
Please take some time to look over the contents of the files in the /srv/babelbox directory that should now have been created.
Note that the default setup assumes your hard disk is /dev/sda. If this is not the case, you will have to do a search and replace before you continue.
Next, add two extra menu items at the end of the grub menu for booting BabelBox:
# cd babelbox # cat babelbox-grub >> /etc/grub.d/40_custom # update-grub
Note that the scripts assume that the BabelBox options will be the 3rd and 4th options in the grub boot menu. You may want to reduce the timeout after you've completed setting up things.
After that there's a few more things that need to be done.
Check the contents of the langlist file. You may want to add or remove languages. The language that has an "x" in the 3rd column will be the one used to set up the next installation; after things have been set up for that language the "x" is moved to the next language.
Set the correct kernel line in /boot/grub/grub.cfg and language name to be displayed during the demo by running ./cronscript script in the /srv/babelbox directory.
The development of babelbox resides in a git repository
- Not all font files that are needed for some languages are included on the first full CD. This means that GNOME can show missing glyphs when the installed system is booted.
As part of a BabelBox run, the third partition of the first detected disk will be deleted unconditionally. You have been warned!
The BabelBox tarball and these instructions have been updated to work with Squeeze.
Instructions for using BabelBox with Etch are available on this older version of this page.
