Yeah, users do want to be able to do image based provisioning, in some
cases with quite complex images. In fact I was discussing with Ian
Mcleod the other day the idea that Factory might need to grow the
ability to invoke Puppet after it finishes running the native
installer when building the image (or running scripts on a pre-build
JEOS). 

Another option, quite seriously, would be to look at having Factory
use Puppet to resolve package requirements just as Foreman
does. Historically we have shied away from this approach because RPM
should take care of packaging requirements... but if we want to build
something that isn't RPM based, well, that won't work. Factory guys,
any thoughts?

There's some interesting work going on with cloud-init that may
eliminate the Audrey requirement. Joe Vlcek is driving that, we might
check with him.
