Background

The critical path is defined as the set of packages required to perform the most fundamental actions on a Fedora system. The list of actions is available at Critical_Path_Packages_Proposal#What_is_the_critical_path_of_actions.3F.

Where can I find the critical path?

The list of critical path packages is a dynamically generated list of packages based on package dependencies. The list is generated daily during the mash process for both Rawhide and Releases/Branched/Branched. For more information on how the list is generated, see Critical_Path_Packages_Proposal#When_and_how_to_determine_packages_within_the_path.

The most recent list of critical path packages are available at:
