Yo can setup your desktop and panel preferences and lock them. To get them the next time you boot, pick up the folder ...../live/memory/changes/root/.kde/share/config and copy it to /rootcopy/root/.kde/share.
To set it for the guest account just substitute root with home/guest and do as before.
When you have it working, you can download 005-kdeapps.xzm and put it in "base":

Reboot and you are done. This is KDE-4.8.2.
Experience freedom!

EDIT: Some dependencies were missing from 005-kdeapps.xzm, so I had to substitute the old link. If you downloaded before 14:20 UTC from April 21, 2012, please get the new version. I apologize.
EDIT2: Now it is Juk that won't start. For that issue add this patch to "modules":

Now you can play your music as before...

EDIT3: A DE without games is incomplete, so I added a bunch of CardGames to 005-kdeapps.xzm and included the patch for Juk. You can download the last version from
http://www.mediafire.com/?yqbf55m9t4q9uqx
Download it and substitute the "old" one (about 15 MB) with this (about 29 MB) 8)
EDIT4: The latest version of Porteus (1.2-rc2) has a new disk-burning program with blue-ray option and without HAL; HAL will be maintained no more and has already been dropped in the 64-bit edition. In other words, we can also eliminate the old good k3b from the 32-bit edition now. I dropped k3b from 005-kdeapps.xzm and made a new 005-kdeapps4.xzm that can be downloaded from
http://www.mediafire.com/?4a8m8pbfdoptdfn
It is now 21 MB instead of 29MB.
Enjoy!
EDIT5: Here is the perfect match to these KDE4-modules: 002-xorg4.xzm with Network Manager in, and wicd out!

Now you can use your android phone as wi-fi hotspot (Barnacle wi-fi tether), connect via VPN, DSL or wired. It should be IPv6-ready, too (not tested!)
Just substitute your 1.2-rc2 version and reboot. The first connection you must edit; then save /etc/NetworkManager/system-connections/Whatever.txt to /rootcopy/etc/NetworkManager/system-connections/Whatever.txt; the next ime you start the machine you will be up and connected automatically....BTW, I also took HAL out; it is deprecated and not maintained and should soon disappear??
