+100000000000, fully agree.

There's too much verbal diarrhoea going on in this thread and no facts.
I've been waiting for real data too, and there's not one shred of it, or
even a hint that it might appear.  So, the conclusion I'm coming to is
that there isn't any data to back up the claims made in this thread.

If it was such a problem, then in the _eight_ days that this has been
discussed so far, _someone_ would have sent some data showing the
problem.  I think the fact is, there is no data.

Someone prove me wrong.  Someone post the verifiable data showing that
there is a problem to be solved here.

Someone show what the specific failure cases are that are hampering
vendors moving forwards.  Someone show the long boot times by way of
kernel message log.  Someone show some evidence of the problems that
have been alluded to.

If no one can show some evidence, there isn't a problem here. :)
