The code to use the first 8 chars of the UUID in the ec2 id was created
and working well, but discarded in favor of a more limited approach. The only
issue was the increased likelihood of a duplicate ec2 id, as we'd be limited to
only 4 billion of them or so. I thought that it would be fairly straightforward
to add code to detect such dupes, and re-generate a new UUID for the instance
in that event. Then we would have no limits on ec2 compatibility, and we
wouldn't need this discussion.
