If there's a weak dep (reccomends or supplants) that generates a solving error, dnf drops that weak dep and goes on with no error? (I guess this case would be two packages recommending things that conflict or one recommending something and another package with a supplants for a different package) 2. For 'very weak' deps (suggests, enhances) does dnf "show the matching packages as option to the user" ? 3. The page says "The depsolver may offer to treat the weak like very weak relations or the other way round" does dnf do that? or not? > However, as people already pointed out, there are no guidelines how > to use this feature and we don't have this fully tested (kind of > chicken-egg problem, we can't fully test it unless it's used in > Fedora). Well, you could test with copr? Or a side repo?

I'd personally say people shouldn't start using this... we should be able to work up the cases or whatever... it just means that in f21 people using yum (the default) will get sometimes different behavior from dnf (not yet the default). Perhaps some folks would like to step up to help out with this? Make a wiki page or document of various cases people might use it, make a test copr with those cases? Draft a FPC guideline for using them? kevin
