On the other hand, writing down guidelines without any prior experience might do more damage than good, that's why I would like Fedora maintainers to give this a shot. We plan to gather some feedback on the Developer Conference [1] to tune up the guidelines. However, what I'm not sure about is whether it's already possible to build weak-deps enhanced rpms in Fedora, has someone tested that? I've heard it's possible in COPR but I'm not sure about koji. > > I have a real-world example where I'd like to mark a dependency as > > Suggests instead of Requires and want to know if dnf is ready to > > process it? > > I played with Recommends in one case and it actually worked as expected. > Even package uninstalls and updates honored the dependency semantics as > expected.

There needs to be some level of support in the layers above but ultimately libsolv is the key part when it comes to weak deps.
