It's allowed me to quickly identify packages like python2 and libsqlite0 that have been left on my system over many years of upgrades. My oldest server was installed in 2009. It's also help identify packages like jlink and zoom that I installed long ago and have forgotten about. Now, I can work on purging old packages and updating those that don't provide their own repos. Zoom does have a repo, but apparently my sources.list was disabled during my last upgrade. Segger, however, only provides binary packages which have to be manually downloaded so I have to periodically check for updates myself. -- Loren M.
