Thanks for the idea.

I finally decided on applying the ultra monkey patches.  My multi-master DNS
is being served off two hosts using two VIPs which fail over to one another.
The zone files are rsynched during normal operation.  All I'm really using
is heartbeat, but I like the fact that I can get balancing now by simply
tossing some ipvsadm lines out.

if you don't need load balancing, you may not need LVS at all.  I've got
a DNS server with fail-over using only the VRRP bit of keepalived.
well, I've actually set it up so the backup director is in charge of the
DNS, it's a nice job for it while it's idling.
