Subject [libcloud] Image formats & configuration management

Hi libclouders,

Following up on Alex's message:

I would like to offer my assistance on this. I started writing a tool
called Clapp [1], which stands for "cloud appliance". It defines a
format for server images which you can actually manage. The idea is to
maintain a single "template" image which is small and version
controlled, then generate images in any format, for any cloud, as you
need them. I've seen this approach implemented on production systems
and it works wonderfully.

In my experience we typically rely too much on runtime configuration
tools like Puppet and Chef, just because the image management
experience is so awful. Hopefully we can change that!

I would love to discuss, and contribute to, anything related to image
management in libcloud. Keep up the good work!
