Rawhide, Fedora development, is a rolling release.
On Fedora 18 TC3, the installer functionally is improved. On the plus side, the hub system gives an user a preview of configuration free to edit. Concerning the partition, developers acknowledge the difficulty to design the layout and the oversight for neglecting upgrade from existing partition. So far, these issue are improving. Let's not forget the release early, release often.
Concerning the delay of F18, remember that Fedora 5 was one of few release with 9 months of development due to major change of infrastructure. Considering the change of board,
mistakes happen which is part of learning experience.
Yea, but rawhide is development version. We would like a rolling release as a 'stable' version.
