That sounds reasonable to me. Stride 4 would mean two years to learn a new name and/or upgrade, which seems plausible. Just to be sure we're interpreting this the same way: X was provided by xorg-x11 in FC-4, but modular packages in FC-5. My interpretation of N-4 would be that the Prov/Obs for xorg-x11 could then be removed in the rawhide cycle between F-8 and F-9. - ajax -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
