cloud-init-nocloud element for non-cloud image Disables cloud-init from querying EC2 metadata, or any cloud metadata service. It keeps only the Nocloud and None data sources, which are both expected to be "baked in" to an image. This speeds up boot by 2 minutes on hosts where cloud-init cannot reach the EC2 metadata service. Change-Id: I43522c4a442c0f2fc2044d4898768ceb4f839099 2013-02-05 05:54:48 +00:00			`#!/bin/bash`

set -e all the things Using set -e in all of our scripts will prevent some subtle bugs from slipping in, and will allow us to enforce use of set -e with tooling. This change also adds -u and set -o pipefail in the less complex scripts where it is unlikely to cause problems. A follow-up change will enable those options in the complex scripts so that if it breaks something it can be reverted easily.

Make cloud-init-nocloud work cross-platform. Previously debconf was used and thus this only worked on dpkg based systems. Now we can support any system that runs a reasonably recent cloud-init.
