Yum replaced with DNF

Yum, or the Yellowdog Updater Modified, is a package manager for RPM-based distributions; DNF, sometimes referred to as Dandified Yum, is the next generation of that package manager.


Yum has long been considered a poor performer. It was notorious for high memory usage, and the slowness when resolving dependencies. DNF now uses libsolv, an external dependency resolver, and hawkey for resolving dependencies, while yum used its own, internal, dependency resolver.
