Luckily, using the live-CD, I was able to download and re-install the "testing" packages for libc6 and friends and finally get my system working again.
OK: 1. Unstable can sometimes get broken. I accept that. 2. However, libc6 stuff is so critical that any upgrade posted must be installable and operational. Some folks might not recover. OK, now much of the x-windows related packages are dependent on the latest libc6 stuff on Sid. As I found out, mixing this stuff will crash X. Since the current packages only partially installed last attempt, I am afraid to upgrade any of this now. What is the status in reality?
