Open Stack

Hi Steve,
Could you post this question on ask.openstack.org? The -dev mailing list 
is not for usage questions; ask.openstack is a much better place to 
ensure that others with the same question will benefit from the answer.

FWIW I'd be really surprised if the version of cloud-init in CoreOS is 
so old that it doesn't support multipart-mime.

cheers,
Zane.

However, it seems like that CoreOS (at least Stable 410.1.0) cloud-init does not support mime multi part yet.
