Image cloning
If you want to apply major changes in the image, its usually a good idea to clone the image before doing so. This way, you can always roll back to the previous configuration. The following command allows creating a new image as a copy of an existing one:
snow clone image <image> <new_image>
Example:
snow clone image centos-minimal centos-custom
