Ben:

It's great to see this fully enabled now.  Will there be any
disadvantages to having all of this running at all times?  Is the
eventual goal going to be to boot into this type of "crash ready" mode
for everyone, or just when someone has a reproducible panic they will be
recommended to install this crashdump meta?
