I have to agree, that seems tasteless. I'd expect something like
triggering registration of devices based off walking down a table of
machine IDs or something. One other issue to consider here is that we
don't want to discourage people from sharing machine drivers while we
can so it can't be completely automatic, it
Perhaps some sort of generic machine type based mechanism for
instantiating drivers a bit like what's done with DMI might be useful,
video will have a similar issue I guess.
