If you are going to astricon you'll want to show up for my talk.  This 
is basically what Leif and I will be talking about.

I use puppet to help manage our 3 environments (test, stage and 
production). Along side it I use a the following configuration setup[1] 
plus some Debian packaging scripts[2].

With this, I can quickly spin up instances which are provisioned to a 
base. Then, depending on puppet manifests[3] for each node, it defines 
how the system is then provisioned.

If more per-site settings are required, I'll roll them into Debian 
packages (we use Ubuntu 12.04) and have each site subscribe to a 
customer repo.
