My normal backup process is to create a new AMI from an EC2 instance I have running Amazon's linux. This is convenient because the EC2 console automatically shuts down the node , makes a copy and brings the old node back up.
The odd thing is that upon starting up the cloned EC2 node, I noticed its ssh host public key has a different fingerprint.
What part of cloning is setting off new ssh host key pairs getting generated.
This is slightly worrisome, because I had created new SSH keypairs into the box and removed the ones Amazon generated and so I do not think Amazon's cloning process could have reached in and done this.
Answer I am looking for: do you know what script on the Amazon Linux does this?
