Has anyone tried out yum RHN plugin from RHEL 5 on RHEL 4 and checked
I use yum/rhn on RHEL 5 lots. It works most of the time. RHN+YUM is
still having a few growing pains, but it's getting better. That
configuration is handled more via the plugin and RHN bootstrap than by
anything EPEL is currently able to provide.
