What I'm was asking then is this: Can udev know that it is running from
initramfs (presumably that can't be too hard) and simply not reply to
async requests it doesn't have firmware for? Then once the real root is
mounted it could satisfy (or not) firmware requests from the real root.

We can surely change it to not cancel the firmware request.

Either by making it aware that we run from initramfs, or by never
cancelling any firmware request and just leave it hanging around for
forever?

I think not cancelling it from initramfs and then providing or
cancelling it once we have normal root mounted should be sufficient? I
don't see how letting it hang around forever (a minute until it times
out) would be useful.

We need to decide what's the best model here, if we want a timeout at
all, if yes, how large it should be, and if and when we should cancel
requests.

I do think cancelling requests still gives us desirable behaviour in
terms of being able to reproduce it etc., it's just that cancelling it
when we have only partial data (from initramfs) isn't helpful.
