Does anyone have an available script or list of commands for removing most or all of these "generally unused" directories, packages or whatever they are?
Ok, here's a two-step process you can try: 1.) rpm -qf /usr/lib/name/of/file/in/one/of/those/directories 2.) yum remove result-from-step-1-without-version-or-release-but-with-arch. Be sure to check the dependencies yum will want to remove, and think it through at least twice before confirming by pressing 'y.'
This is a diesel piledriver of a solution, but..... do be careful you aren't trying to remove something really important.
As an arbitrary and simple example: [root@localhost ~]# cd /usr/lib64 [root@localhost lib64]# cd firefox-3.6 [root@localhost firefox-3.6]# ls application.ini chrome extensions langpacks README.txt blocklist.xml components firefox LICENSE run-mozilla.sh browserconfig.properties defaults icons modules searchplugins [root@localhost firefox-3.6]# pwd /usr/lib64/firefox-3.6 [root@localhost firefox-3.6]# rpm -qf application.ini firefox-3.6.26-1.el6.centos.x86_64 [root@localhost firefox-3.6]# cd .. [root@localhost lib64]# yum remove firefox.x86_64 Loaded plugins: fastestmirror, refresh-packagekit, security Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package firefox.x86_64 0:3.6.26-1.el6.centos will be erased --> Finished Dependency Resolution

Here's a more concrete (if extreme) example, since the python-2.6 directory in a default CentOS system isn't small (do note that I've snipped out several hundred lines of output with points of ellipsis (...) but left in lines that show real dealbreaker issues.....):

In other words, you can't remove /usr/lib64/python2.6 safely..... unless you want the basic 'yum' command to break....and want to remove the bootloader.... and want the cluster manager (cman) to quit working.....
But python2.6 accounts for over 11% of the space in the /usr/lib64 tree.....
