Thanks, Lamar. This is the type of helpful response I was looking for. If anyone has any other practical "lists of junk" please post them. My goal is to develop my own list, put it in a basic shell script and remove them wholesale. I've done this for generally unused services which I run upon installation of a basic system, and it works well. The more community input, the better, IMO. Thanks again.
