Amazon EC2 now supports using an EBS volume for Replace Root Volume

Today, AWS announces Replace Root Volume using an existing EBS volume, a new option for replacing the root volume of a running Amazon EC2 instance. Customers can now use an EBS volume as the target for a root volume replacement, in addition to the existing options of replacing from a snapshot or an AMI. This option supports customers running stateful workloads who need to include specific metadata or software on the root volume before the application boots.
