This copr currently has zchunk and createrepo_c in it. I did have to disable the python tests for createrepo_c which means I probably wouldn't use the python bindings with this release. https://copr.fedorainfracloud.org/coprs/jdieter/zchunk/ To enable zchunk creation, run createrepo_c --zck. I've created dictionaries that are appropriate for Fedora's metadata at https://www.jdieter.net/downloads/zchunk-dicts, and they can be used with --zck-primary-dict, --zck-filelists-dict and --zck-other-dict. To make zchunk downloads efficient, the same dictionary must be used each time metadata is generated. Dictionaries aren't mandatory, but they greatly reduce the size of the compressed metadata.
