Yes, but in this case Roberto ran "make delete-old" *before* installing world, on your advice. That is definitely something that should be avoided. E.g., "make delete-old" should only ever be run with exactly the same source tree that your current world was installed from. And preferably right after "make installworld" and updating /etc. -Dimitry
