Subject Re: Functional Specification for the multiple IPs per NIC
Date Tue, 18 Dec 2012 18:56:01 GMT
cloud-init's (more specifically, user-data) being mentioned because I see an ongoing need of
wanting to get instance-specific data into an instance.

So, we can tweak meta-data to add support for multi-IP per NIC (MIPN), or we can take a step
back and talk through how the metadata side of things could be beefed up before implementing
MIPN to minimize future rewriting.

The result is better compatibility with AWS, better security, and more standardized functionality
going forward.

Yes, this is a separate feature than the MIPN by itself. I meant to call that out in my first
bullet, apologies.
