Only one person showed up to discuss the topic: Patrick Debois. Their discussions and sharing of ideas with others advanced the concept of "agile systems administration". Debois and Shafer formed an Agile Systems Administrator group on Google, with limited success. Patrick Debois did a presentation called "Infrastructure and Operations" addressing
