I have personally always been under the impression that when dnf was
ready to be a yum replacement it would all be renamed to yum. though
there is still a lof of areas we will have to work on before dnf can be
a replacement. I am not away of any work to make mock use dnf. dnf will
need to be able to make mock chroots going all the way back to rhel5
since we use mock in the buildsystem and we build epel5 there.

I really think forcing users to use dnf as the command is going to be a
lot of needless retraining and redoing of work.
