And retain yum for compatibility It still relias on the same
fundamentally over-engineered upstreadm repository metadata, it's
mostly compatible with yum except at the unpredictable moments when it
is not, and it still can't do an uniinstallation of one package and an
installation of another package in the same step to manage common
dependencies for packages like "sendmail" vs. postfix, Java version
migrations, and "mysql-libs" changes between MaradDB, Percona MySQL,
community MySQL, and others.

I'm afraid that dnf added features that break things and didn't
actually solve any of the already existing, long-standing problems.
I'm quite upset with it: it's now breaking SL 6 and SL 7 hosted builds
using mock for the most recent Fedora.
