I work in a computer science group in a hospital, we constantly run ins like this with the IT group and we would deal with an issue like this by saying a straight out no. We manage our own servers, if IT screw them up then our systems are up the creek and we get shouted at. It is worth pointing out that we try to keep as upfront as possible with IT about ongoing projects that will directly influence their infrastructure i.e firewall etc.
I totally agree, unfortunately i administer a few centOS boxes at work. This will be bought up and i will argue for moving to a more open community distro which is a shame because i quite like centOS - however if it can not be relied upon like that it just looks bad.
