(Well, except for starting privsep daemons, oh and of course
os-brick wants to know what our root helper is for some reason
that is a bit beyond me.)
Yes that's right, we now live in the future and no longer need
the run_as_root infrastructure in nova.utils. I'm sure this breaks
some out of tree drivers, but they've had several releases to
notice that we're moving in this direction and its pretty easy
for them to fix themselves these days.
