This feature helps keep database very clean and allows easier move of xCAT master from one host to another (define xcatmaster hostname on as few places as possible). Also will help HA setup.
Backwards compatible if not used. Has to be tested if used with service nodes.
In our environment we wanted to make xCAT highly available. Instead of some cluster solution we decided to install two independent xCAT masters. Using this feature we can have exactly the same xCAT database on two dirrefent nodes, so it's possible do backup on on node and restore on other node.
Usage example is in HA cookbook (TBD).
