chunks. This allows you to only download the differences when downloading a
new version of the file, and also makes zchunk files efficient over rsync.
zchunk files are protected with strong checksums to verify that the file you
downloaded is in fact the file you wanted. ebuildvm-ppc64le-23.iad2.fedoraproject.org Fedora Project Fedora Project BSD-2-Clause AND MIT Fedora Project Unspecified https://github.com/zchunk/zchunk linux ppc64le ` X
