[StarCluster] starcluster createimage

[Ranjit Chacko]

I'm also having some trouble with the createimage command.

I created an instance through the AWS console, made the changes to the 
instance I wanted to save, and then tried the createimage command.

First I got a warning:
WARNING - Creating an image from a StarCluster instance can lead to 
problems when attempting to use the resulting image with StarCluster 
later on

cli.py:517 - WARNING - The recommended way to re-image a StarCluster AMI 
is to launch a single instance using either ElasticFox, the EC2 command 
line tools, or the AWS management console. Then login to the instance, 
modify it, and use this command to create a new AMI from it.

I believe this is what I did, so I'm not sure why I'm getting the 
warning. Does this mean the initial AMI I want to rebundle can't be one 
of the StarCluster AMI's?

Then an ssh command fails apparently because it does not have the right 
user id. What is the appropriate user id to use here? Is it the 
canonical id, or the AWS account id?

Thanks,
