I'm also happy, and I want to upgrade soon. I hope many of those little 
annoyances I experience will be fixed.

Yeah.

I did that, too, but got errors from portage (Error during set creation: 
Redefinition of set...). Looks like the sets are found in the kde-testing 
overlay, so I removed them from /etc/portage/sets, and all was fine. Coool.

Not really necessary I heard.
But: I am still using the dreaded kdeprefix use flag. It sounded like a good 
idea to use it, and I would also like to have different minor KDE versions 
alongside. Okay, it's hard to maintain, I understand it will be dropped.
Now, do I REALLY REALLY have to unmerge all @kde-4.2 first, remove the 
kdeprefix use flag, and proceed to step 3?

Hopefully this runs through. If it takes a night, it's okay, but if it stops 
in the middle, I have no KDE for a while. And I need much of the stuff in 
there, like the wallet with its passwords.

What about this: I update my system's backup (I'm using rdiff-backup), 
chroot into the backup, sudo to my account, and issue startkde. Could I get 
a running KDE 4.2? Then I would have time to install 4.3.

I really hope I can just copy .kde4.2 to .kde4 and all (okay, most) settings 
will be kept. I think it just _should_ work. Customizing all over again 
every time a new KDE arrives would be no good.
