Restoring AWS Image

I ran into an issue and think I have a solution, although if anyone has other thoughts, please let me know.

I'm developing a workflow to create Aegir sites on Amazon EC2 instances. As part of my development process, I make incremental images and when I inevitably blow something up, I create a new instance using my last image. At first, it looks like everything is fine, until I try to verify servers and sites and I get a bunch of rsync errors.

As the excellent documentation at http://community.aegirproject.org/installing/debian points out, a fully qualified domain name (FQDN) is needed for an Aegir site and that's where the issue comes up: the new instance has a different hostname from the original. The solution is to replace the new hostname with the original hostname as per the documentation.

I hope this helps someone, and if it is wrong, like I say, please let me know.
