Thanks you all for the help! I usually do pay attention, and I prefer sid even given the risks (it's great). I don't need the machine at the moment, so I'll just wait for the transition to complete.
Using snapshot repositories and "apt-get install packagename=version" sounds like a *great* strategy to implement a quick-and-dirty rollback function for apt-get. Do you think it would suffice to analyze history.log and run "apt-get install" with - "package-" for all packages installed by the last update and - add "package=version" for all updated and removed packages? The snapshot it would use is the one of the previous upgrade.
