Comment 40 for bug 285746

phenest, the "residual config" was planned for jaunty, but didn't make it, so it'll happen for karmic instead. It is a good idea, although not entirely risk-less.

CJ already separates between 'local or obsolete' and 'autoremovable'.

Jan, changing gdebi to whitelist packages would be a nice first step. It's not a complete solution, though, since not everyone uses gdebi. But it would be a step.
