I’ve said it before that I’ve always been a huge fan of SystemImager, for super simple imaging. It has some shortcomings for config management, but those are solved with things like Chef or Puppet.

That’s One Thousand One Hundred and Ninety nodes. Completely installed in: Fifteen. Fucking. Minutes.
