Debian only. The problem here is that the first time the galera is started it must be done with some specific option, ie "--wsrep-new-cluster". Then it shouldn't be used anymore. This has to be used only on one node or else all nodes become master. To achieve this behaviour a specific mysql init script is installed: mysql-bootstrap. This script check if the galera has started and, if it's not the case, it adds wsrep-new-cluster to the command line. Then in puppet I change the service name for mysql to mysql-bootstrap on one node. The port to RHEL could take the same road. The only requirement is that: $ strings `which mysqld` | grep wsrep-new-cluster be true. I don't add the close 11 to it as the rhel support should come with it I think. issue #11
