[Yum] No redhat 7.0 support?

[Roland Glenn McIntosh]

Hi! I've successfully upgraded my RedHat 7.0 system packages to the following using rpmfind.net:

	glibc-2.2.4-18.7.0.9
	rpm-4.0.4-7x
	rpm-devel-4.0.4-7x
	rpm-build-4.0.4-7x
	rpm-python-4.0.4-7x

I installed yum (1.0.3).  Unfortunately, there doesn't appear to be a repository for 7.0.  Does anyone have any suggestions for me?  I'm quite new, but I read the man page.
I'd like to eventually use yum to upgrade some necessary stuff (mostly a new ssh).
