I did this some time ago and ended using the "stupid" method. So if there's a better way than what I'll describe, please someone step in. What really matters when you rename your master is your master SSL certificate. Clients will be verifying if the puppet master's hostname matches the one advertised by the certificate. So when I changed the hostname, I had to create a new certificate for the master, and then recreate certificates for clients and "re-registering" all clients to the master. e.g.: on all clients: * wipe out /var/lib/puppet/ssl * run puppet agent -t --waitforcert 10 * on master, sign client certificate this was very time-consuming though. now if my imagination is not too far off from reality, there might be a way to tweek your master certificate so that it has more corresponding hostnames (think certificate for a web server that matches multiple domains). it might not be applicable though :\ -- Gabriel Filion
