And what about old libraries?
We used to have a little disclaimer that upgrading was not equivalent to wiping and reloading with the new version; yes, stuff will get left behind. It was decided the upgrade docs were too big and scary so that was one of the things removed to shorten it up (see older versions, like upgrade55.html, for example). Things that are out-right replaced (i.e., sudo) should be actively deleted. Even if it still works after upgrade, some day it is going to break, and you should be pushed to use the new application (or the package of the old application). Things like tip? what's the point? case 1) It still works. No harm done. case 2) It no longer works. useless file on system...so what? Either way...no harm. Library files are far more "interesting"...depending on the upgrade, they still may work with old packages still on the system. Delete them, you have broken the old packages before you got them upgraded, usually no big deal, but sometimes, may really annoy you. Again... who cares? Yes, after ten upgrades, old libraries can start to add up, but on a modern system, you will go through a lot of upgrades before you can save a GB of data deleting old stuff. Just not worth the trouble. Quoting upgrade55.html: "However, the results are not intended to precisely match the results of a wipe-and-reload installation. Old library files in particular are not removed in the upgrade process, as they may be required by older applications that may or may not be upgraded at this time. If you REALLY wish to get rid of all these old files, you are probably better off reinstalling from scratch." If OCD is causing you to twitch at seeing the old files, reinstall...or use this as a therapy. Nick.
