We try quite hard to keep our stack homogeneous. We're Debian Squeeze from dev through to deployment, except for a very few Lenny services which haven't been upgraded yet (and won't be, until the service itself is replaced). This means that getting a new service up and running should, by and large, be trivial. There's no discussion over what the best platform for a given service is, it's just a question of how to get it working on Squeeze. If we have to package something up to make it deployable, that's what we do. Anyone coming to an arbitrary system knows what the tools are, and where to look. It's very, very simple.
