[arch-projects] [dbscripts] [PATCH 2/4] Add reproducible archive of packages.
Whenever adding new package files to the pool of distributed packages,
hardlink a copy of every package it was built with, into a
"reproducible" pool, and log which file required it.

The question becomes, where can I store these? As-is, this will burden
the mirror network as well. Unsure how to handle this. Could this be
configurable by the mirror, as ISOs are now? Should we exclusively
self-host this, and if so, where?
archive.archlinux.org is managed by another service with its own
exclusively writable location.
