For me, it's a big improvement, especially when it comes to keeping the clock correct in the vm.

Users seem to have a problem with more than 1 item of the same type in a specific repo. We will put out instructions on how to use "exclude=whatever" in yum, but they don't and then we get a hundred bug reports / e-mails that the plus kernel replaces the vmware kernel or the other way around. If we can have them easily coexist in the same repo and make it EASY for the users and provide the content, then we will put them there, otherwise (or until then) people will need to look for it here.
