The more variation there is between the development (user space) bits inside the container and 
the host layer (kernel space) bits it is running on, then the more you have to carry around
in the container.

Remember that OpenStack was originally built by RackSpace and NASA to counter AWS.
Naturally, in fine NIVH fashion, the OpenStack community wrote another configuration
management tool (Heat) rather than using cfengine, Puppet or Chef (don't think Salt was
around yet).  Now it is starting to look like the tool of choice is none of the above, but
rather Ansible (and I'm not saying that just because RHT owns it now).  It seems to be
gaining quite a following in the OpenStack space.

McCarty must be heads down getting ready for Red Hat Summit as I would have expected him to
chime in on this.
