I got started with Eric Hammond's great article over at http://aws.amazon.com/articles/1663 where he goes through installing MySQL and configuring it to use EBS. I got that going. I also have a lot of other stuff installed on that EC2 instance: Rails, a bunch of gems, Nginx+Passenger and so on - my understanding is that unless I explicitly configure it to use EBS, all of this sits on the EC2 instance's ephemeral storage - right? How can I move all the software I have installed to EBS - or better yet how can I set up such that going forward also any new gems etc that I install also go to the EBS volume?
