So you suggest initially populating old/ and then symlinking the
now-current version in the main download directory at the old/
target, instead? It would still initially download the package
twice, and then simply unlink it later on, right?
Or what's the right approach here?
I suggest moving the old directory out of dist completely and instead
put old distributions under history.apache.org (not mirrored). That
way the rsync'ers don't have to sync gigabytes and will simply delete
the files that are no longer worth being mirrored.
