Puppet Faces are an extendable API for tricking out your Puppet instances. (“Faces” is just short for “Interfaces”.) Just a couple days ago I wrote about my survey of puppet + ec2 provisioning tools.
The problem I’m trying to solve, which I don’t feel like I’ve solved well, is how to give a type to a new system at bootstrap time, without using DNS. The type variable maps to a node manifest group, and determines the personality of a host – is it a database, webserver or development instance?
