It is particularly useful on systems that mix packages from different releases (stable/testing/unstable) and on desktop systems where packages are frequently installed or removed according to evolving user tastes. . By default, it is configured to purge all packages that are not listed as another package's dependency. Less drastic settings are possible by editing /etc/upgrade-system.conf(5).
