up2date uses yum headers that are created by yum-arch ... where as yum >

createrepo.

If you used yum-arch to create yum headers for your local yum repos,
then you can adjust up2date (and therefore also rhn-applet) to use a
local repo by adjusting /etc/sysconfig/rhn/sources.

up2date can even use (though not very well) createrepo metadata using
the repomd type repo .. however, rhn-applet will not work that way.
That is why the centos mirrors have both yum-arch and createrepo type
metadata.

Remember that yum (and not up2date) was designed as the primary method
for package management for CentOS.  Up2date is provided with the RHN
parts removed, and is functional, but yum is recommended.  In fact,
up2date would not have been retained at all if it were not for the rhn-
applet.
