I'm not quite sure I'm parsing your sentence correctly. If you're preseeding with debconf the value is that you got to preseed the correct configuration options. This means the debs will work with anything, not just the flavour of the week devops tool. Juju, Puppet and Chef aren't the only games in town. I'll agree that they are all very useful tools, but you shouldn't need to write complex scripts/manifests/whatever around them to stand up services. That should happen out of the box without requiring anyone to jump through 50 hoops. It also means that you can scale from 1 instance all the way up to 5000 instances which is a lot better than optimizing for the 5000 instance case. I'll definitely give you a shout on IRC.
