No, this post is just referring to using rsync to synchronize the 
static part of the config file that is normally the same between both 
the primary and slave in the failover pair.  You still have to run 
failover protocol in the DHCP server.

I wouldn't characterize the dhcp failover implementation as "buggy" 
anymore.  All the serious bugs got worked out long ago.
