It blocks some cleanups I'd like to do which rely on it being truly gone, not just sometimes-gone. I think it's reasonable to do this, since the "raw" rtas blob from qemu was never supposed to be a guest visible artifact - any guest that was relying on this was going out of its way to be fragile. --=20 David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
