I'm just curious what's the most expensive thing for Koji to implement
side-tags, I'd expect something like:
- the repositories are cloned (recursively hardlinked/symlinked?)
- the override package is added
- then createrepo_c is run
In Copr we don't have to clone the repositories, but we have to run the
createrepo_c after each build. In the past the bottleneck used to be
the createrepo_c run (recursive walk through all the packages in larger
repositories).
If Koji suffers from the same problem, perhaps you could take a look at
the new createrepo_c option `--recycle-pkglist` - the createrepo_c costs
almost nothing then (matter of just reading and later writing the xml
metadata).
