I've been experimenting with yum and up2date. They both appear to have their merits. I've got a couple of additional questions. (1) Is it "safe" to use both yum and up2date? It *appears* that one recognizes changes that were made by the other. Is this always the case? Or can you get in trouble if you don't stick to one or the other? (2) What is the best way to go about finding the "right" repositories to use? Both in terms of getting the "correct" updates, and also in terms of not generating undue traffic?
