I suspect that only a small fraction of your installed packages don't have files in /usr, so the above method probably won't be so slow. One thing that could speed this up is to make sure debconf only asks you "critical" questions and does not re-ask questions you have answered before. Before trying to reinstall everything select these options by running: dpkg-reconfigure debconf Additionally will probably find that some of the packages are no longer available (unless you run stable). So it might be best to put the package list in a file, and edit out the packages that apt-get complains about. eg 1. dpkg --get-selections | grep -w install > pkg.txt 2. apt-get install --reinstall `cat pkg.txt` 3. Delete entries in pkg.txt, go back to 2.
