This update fixes several issues with systemd service ordering and network configuration. It also backports a fix for a security issue in which instances run in EC2 write IAM instance profile credentials to disk. To work around the security issue without updating cloud-init, wait at least six hours between creating a bundle or an EBS snapshot and registering that as a machine image.
