For mission-critical systems, I would have done a clean re-install already with data copied back from a backup. More then 24 hours is a deadline. For non-critical, I am willing to invest more time. > > I wonder if I speak for more users when I say that all this is kind of > > confusing sometimes ... > > I'm with you there, Stefan.
