I've switched back to Yum for now.

Is DNF within Mock a fully compatible replacement for Yum yet?
It seems builds take much longer now since something's downloading
(or redownloading?) lots of data for each build job before setting
up the buildroot. I don't have much time to look into it, bug shouldn't
Mock's buildroot cache files be fresh enough to avoid redownloading
packages, for example?
