(Yeah, spotted that one earlier. :)) I'd be tempted to do the .ko thing at d-i build time (we already have a few other things in a similar-ish way) and the firmware-intel-sound (but not firmware-intel-graphics) at cd build time. Are you happy to give an iso a shot? Cheers, -- Cyril Brulebois ([email protected]) <https://debamax.com/> D-I release manager -- Release team member -- Freelance Consultant
