Chef uses the "node_name" value for the "client_name" when it  
registers the new client with the API.

By default, the "node_name" comes from the FQDN as detected by ohai  
(via hostname -f). You can override this setting in the client.rb by  
setting node_name explicitly:

% grep node_name /etc/chef/client.rb
node_name "web1prod.example.com"

This isn't easily managable or scalable but for a one-off system it's  
okay.
