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.
This has implications on another Change - moving to Python 3. See
Scope section -
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
