Before doing that, there's a question of whether we're going to support
'noarch' "properly" (ie, with a single build/package upload for all
If so, it would be necessary to compile a single list of files for
Checking it against linux-firmware I get results along the lines of
- one third of the firmware is 'missing' (ie, not in linux-firmware)
A large chunk of this is in alsa-firmware and other packages.
- the remainder runs just over 40 megabytes
- there's lots of firmware that seems to be 'unneeded' even though the
relevant drivers are enabled (eg, only 2 files from brcm/ of 24 are
needed), which makes me wonder if something's wrong with modinfo...

*If* the results are correct, it wouldn't be *needed*.
