xcat-core/perl-xCAT
History
sikorsky 14600652bf Added special expressions for database table columns. Currently supported are "{hostname}", "{xcatmaster}". Any expression in braces is evaluated and replaced with some interpolated value. If expression is not defined, it's replaces by itself (ie. braces are deleted). 
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).
