RPM packages of MariaDB-Galera are not available in yum repositories after a new version of the main server gets released

Our repository configuration tool provides a generic link for both MariaDB server and MariaDB-Galera, e.g. http://yum.mariadb.org/5.5/centos5-amd64

Main server and Galera server are not released in sync, so, as soon as the main server is released, the link starts pointing at the new version, which does not contain MariaDB-Galera-server, and yum install can't find Galera server anymore.

We need either to have different repositories for server and Galera-server (which in turn might cause problems), or be careful placing the last released version of Galera-server, whichever it is, with the last version of the main server.
