That is one advantage of the way automirror worked, since it was specific to yum it didn't mind the mirror configuration.
Yes, would be nice if it worked for me :-(
One way around the mirror list issue is pointed out by Guru labs (though I admit hijacking the DNS seems heavy handed)

I'll look at it. I just installed the "yum-downloadonly" on one box and am starting the upgrade with that flag enabled.
Then I suppose I can mount the cache directory on other servers before updating them and I should be golden
Given that I've only got 5 or 6 boxes to do it should not be a major problem.
But I'll look at the link above as well
