This request is not so much a coding request than an operational request.
The next time there is a release, let's make a full copy of the entire Arch LInux ARM repository on that day. Reason is pretty simple, with the Rolling Repo strategy used by ArchLinux, and the fact that a RuneAudio release can not (rightfully so for QA control) be upgraded to the latest components, we need to find a way to "freeze" the release's packages and be able to install kernel sources and headers (for example) a year after the RA release, and have the ability to compile and build new code, kernel modules, etc.
Real life example : I wanted to have the OverlayFS module to make the entire RuneAudio install base read-only and make a SD-crash - resistent setup.
