Do you *actually* mean that you would prefer a package manager that always chooses the same package regardless of what the user has already installed? If Gizmo requires frobnicator, which is provided by both Gnome-frobnicator and KDE-frobnicator, and the user has only installed KDE, do you really want Gizmo to pull in half of Gnome even though it works fine with KDE? I can't believe that you would find that acceptable. But if you actually want that – from a developer's perspective – then it's dead simple to achieve: Just don't use virtual provides. Write "Requires: Gnome-frobnicator" in Gizmo.spec. Problem solved; no need to replace the package manager. > If we want package maintainers to be able to actually choose what provider > gets picked by default, all those complex heuristics must be replaced by > something simple and dependable (e.g. 1. prefer same arch, 2. prever newest > Provides version, 3. prefer shortest package name, 4. prefer first package > name in the alphabet, period). That algorithm would prefer KDE-frobnicator over Gnome-frobnicator, which is undesired in Gnome-only installations, but it would prefer Gfrobnicator over Kfrobnicator, which is undesired in KDE-only installations.
