> Our policy was that update media should be self contained.

that was the mdv way, yes.
but it's bad, as it adds duplicate rpms on the mirrors & bigger hdlists in updates tree.

yes we could hardlink rpms, but it would need more complex setup on the primary mirror side, and it wouldn't help with the hdlists

The "add updates only" media option should be dropped from rpmdrake/media manager.
We now tell people to add all online medias to get full support.

Adding full medias only need to download the /release hdlists once as the medias are frozen.
