There is in fact no strict *technical* requirement for anything to 
move from yum to dnf in F22. yum will remain in the F22 package set, 
it is not being removed.

However, the Change seems to me to have been written with the basic 
idea that yum shouldn't be installed by default any more and nothing 
that's a core part of Fedora should use it any more - for e.g., the 
Change incorporates moving anaconda to dnf, even though technically 
speaking there's no *need* for this, we could if we wanted to ship F22 
with anaconda using yum but the installed system using dnf.

So given that, I wanted to clarify the status of fedup.

If F22's fedup depends on yum, then people with 'clean' dnf-only 
systems are going to get yum installed when they want to upgrade to 
F23. Of course, we could ship F22 on release day with a yum-based 
fedup then provide a dnf-based one as an update, but that seems a bit 
messy.
