Hello Edubuntu community,
The Edubuntu team is happy to announce Edubuntu Flight 4, the 4th
milestone CD image in the Ubuntu 6.04 "Dapper Drake" development cycle.
You can download Edubuntu Flight 4 from the following mirrors:
* United Kingdom, and the rest of the world:
A list of other mirrors are also available at:

Apart from the notable changes in this release that apply to all Ubuntu
flavours, which are listed at:
the following additional Edubuntu-specific enhancements have gone into
this milestone release:
LTSP Flight 4 Featurelist:
* PowerPC support was added. Please note however that there is
still a small bug in the chroot handling in the client chroot
builder of the installer, please run sudo ltsp-update-kernels
manually after installation.
* The multiarch code saw plenty of other improvements and fixes.
Less Memory consumption
* LTSP now finally supports the X_COLOR_DEPTH variable to force
the usage of 16Bit on the clients through lts.conf.
* By default we now install only the linux-image package in the
client chroot, the excessive memory usage of the restricted
modules package is gone
* A special netboot mode was added to initramfs so only network
device drivers are loaded, this reduces the size to two thirds
of a normal initramfs
Serial Mouse Support
* LTSP now understands the X_MOUSE_DEVICE and X_MOUSE_PROTOCOL
lts.conf options and adds support for various serial devices
from ipaq touchscreens and over plenty of mouse protocols up to
some serial tablets.
* 3 button emulation of 2 button mice is now supported as well.
* The bootprocess has seen further speed improvements, lts.conf
values process code only if they carry a value during startup
* As mentioned in a previous section, netboot mode speeds up the
loading of the initramfs through the size reduction.
* Startup links in rcS.d and rc2.d are now started based on
whitelists (RC2_WHITELIST RCS_WHITELIST), only the bare minimum
of processes is started on the thin clients - this results in a
* Usplash was included and enabled by default, got better default
values to prevent it from timing out on very low level clients,
you will have bootsplash love all over now :)
* Many patches were merged from the debian team to make the
packages work on debian as well.
* Sound support saw some smaller changes and bugfixes
* The ltsp-build-client script now has options to manually enable
extra and security mirrors during chroot creation.
* The default mirror of ltsp-build-client points to
We have working LiveCDs for all arches! Enjoy !
The new artwork infrastructure is in place, you will be able to easily
select your theme by age once we have the artwork in place.
Current known issues and bugs in this alpha release include:
* PowerPC LTSP support is still experimental, see the features
section for more information.
* As previously mentioned there is a bug in the chroot handling in
the client chroot builder of the installer, please run sudo
ltsp-update-kernels manually after installation
