Re: building an ami corrupts the original reference machine?

Glad you got it working. I had no idea about the difference between the
two versions regarding AMI creation. For AMI creation, I find it easier
to use the console. This way I can label and provide a detailed
description of the AMIs I create and label their corresponding snapshots
in the same way so that I have an easier time deleting them when they
are no longer of use to me.

Good Luck!
