Propellor is a configuration management tool whose config file is written in haskell.
This short workshop will show off some of the neat results, and perhaps one of you will turn out to be user #3.
Rather than studying puppet or chef to learn from them, I made propellor up as I went along. So, this is also my chance to get told how I'm doing it all wrong.
Also, bonus ascii art! And possibly live onstage destruction of my DNS server.
