Hi. I'll add myself to the wiki list in the next couple of days.
I'm interested in attending. I've worked on image creation with Debian and other operating systems since around 1992 or so. I've been the architect for a product that managed a bunch of Debian appliances in the cloud and been responsible for image generation for that. Currently I'm working on image production for my employer; most of the consumers of those images are not actually cloud for the current round of our product, although that will likely change. At this point I'm quite familiar with live-build and vmdebootstrap and have started looking at bootstrap-vz anz, so I think I would be a good participant for comparing the various tools. Also, I think it would be great if someone on the Debian technical committee understood what was going on in this space and understood all the complex tradeoffs. I'd be happy to stay up to speed in that role. --Sam
