Use DNF rather than PackageKit on Fedora

Fedora Workstation comes with two package managers by default: DNF and PackageKit. DNF has all the latest features and the best support, but PackageKit is put front and center in GNOME Software, KDE Plasma Discover, and as of Fedora 26 also in Cockpitis new Software Update panel.You may be better off sticking with the DNF package manager in the command line; even though PackageKit is the choice of all the graphical package managers. Here is some of the advantages DNF still gives you over PackageKit based applications.
