Yeah, I've got some really good feedback -
There are some tools (synopsys) which read the /etc/redhat-release file to ensure they're running on a supported OS. I've had exceptionally good luck by simply replacing that file with an official redhat one, and letting the tools run on centos. However, official redhat has some proprietary code in it. I got burned by this. Dell Openmanage is the only way to replace a failed disk on a dell server without shutting down into bios, and it doesn't function on the "open source equivalent" of some package. So I can say that for sure - if you're using dell branded servers, then use genuine RHEL. But if you're using blackbox servers, you could probably save yourself some money. Aside from the logo, and the /etc/redhat-release file, and the (rare) instances of something working on RHEL but not centos. The only other significant difference is that the filenames of the rpm's are different. So if you script something, you have to account for that. Or you just mix 'n match packages (install a rhel package on centos or vice versa). I do this sometimes, and have never had any problem with it. And also, up2date versus yum. Is one better than the other? Maybe, but it's not a huge difference.

I'd love to hear from anyone who has operated both and any insight you can share on this topic. My desire to know more about this topic pre-dates the Drama over at http://centos.org, however that drama has added motivation to ask the question sooner rather than later.
