I went in to work yesterday and since I didn't have a client assignment, I started doing stuff I found useful (hopefully others will too.
I found an old Win2K machine and brought up Fedora Core 2 from the ISO images I'd burned a while ago. Then with the wonderful yum.conf from the Fedora FAQs, bringing everything up to speed was just a matter of typing yum update. I haven't used a tool like yum before, and I'm very impressed. All updates should be this easy. It even updated my kernel correctly.
