It already does this.  There is a built-in ping system in the load 
balancing and failover.  If this is not working there is a bug in the 
config that needs to be fixed.

Last time we had issues it's been the DHCP address handout that seemed to 
be the problem, not the link failover.

I can easily just turn off the TCP load balancing and send all traffic 
over monkeybrains and only failover to sonic if the monkeybrains ping 
monitor fails.

The Vyatta configuration is backed up automatically to minotaur by a cron 
job.  See /var/backups/bikeshed.noise/
