Description
Amazon recently released version 2 of their instance metadata service. The new service is session-oriented rather than a simple request/response HTTP call, and was created in response to recent security breaches.
Facter currently only seems to support version 1 of the metadata service for the ec2_metadata and ec2_userdata facts, making it difficult for Puppet users in high-security environments to transition to version 2 of the service.
