Package management system

DNF or Dandified Yum is the next generation version of the Yellowdog Updater, Modified (yum), a package manager for RPM-based distributions. DNF was introduced in Fedora 18, and it has been the default package manager for Fedora since version 22. Perceived deficiencies of yum which DNF is intended to address include poor performance, high memory usage, and the slowness of its iterative dependency resolution. DNF uses libsolv, an external dependency resolver.

Contents

It does package management using RPM, libsolv and hawkey libraries. For metadata handling and package downloads it utilizes librepo. To process and effectively handle the comps data it uses libcomps.
