Dan, where can I find how to do something like this for ec2 nodes?  Is the recipe available somewhere?

Thanks.

I ran knife with the -N option with the parameter set to 'www'. However, the

doesn't quite do what I want it to do. I want the actual hostname of the box to
be www.

Otherwise, in a template, how do I get the node's name (for populating
/etc/hosts on all machines)?

By setting the node name via -N, you should create the node and it's client with the given id, and configure it to use those values instead of the hostname. Then you're free to change the hostname without changing the ID the node uses to identify itself with the server. So you could create a cookbook to configure the hostname according to the node name. This is what we do for our EC2 nodes, except we use the instance ID for the node name and generate the hostnames from the roles. But the basic idea is the same.
