fw_update is the first time we actually depend upon internet working.
I've seen it not work, and I've seen it slap against a proxy for a while
thinking it will work.  Regardless, let's say it times out.  (Meaning,
we must make sure it gives up quickly, and nicely.  I think afresh1 designed
that into the new one).

In that case, do you have the files neccessary to proceed?

If we do, that's OK.

So it mostly comes down to fw_update must not hangs. If it hangs, people
hit the power button.  Now the machine is not bootable.
