We just need a step to retrieve, save yum metadata. Possibly, we may have to mangle base url but it's easy to do (yum metadata are just sqlite and xml databases). > What i'd propose is to have versioned dependencies repos so that jobs > can easily report the version of deps used and replay the job with a > specific dependencies snapshot if needed. > Just to clarify to the readers, we don't need to version the whole repositories only the yum metadata. By convention, published packages are not removed from public repos, and yum/dnf won't see newer packages that are not in metadata. So it's quite a storage-efficient way to handle the issue mentioned by Wes.
