Our results here are admittedly a little different from what we expected. Although I love apt as much as the next guy (moo), I never considered it a configuration management tool. Whether it was meant as a non-answer (I don't need no stinking configuration management!) or a desire to include configuration into deployable packages, apt was an unexpected winner. It also was cool to see Subversion, as I have heard of people using it for managing configuration revisions, and it's neat to see evidence of that reflected here.
