[chef-dev] Idiom for adding a node to a Cluster

[Bryan Taylor < >]

I'm wondering what the chef idioms are for a certain problem that comes 
up a lot when expanding a cluster. Let's say I have some kind of 
persistence store and I want to enable replication, or add a new node 
with replication to an already running cluster. The replication will 
communicate on some custom protocol, but in order to work, I have to 
move stateful data, like db logs or whatever, from the master to a new 
node. The master is "the master right now", so it needs to be 
dynamically discovered, and accessed via rsync or scp, say,  to pull the 
files down. I'm thinking for this I should just provision every cluster 
node with a fixed static public/private key.
