Ah... put it will also failover all the OTHER carp interfaces on the box
when a physical interface goes down.... I had read the man page as that
being the ONLY feature of that sysctl variable.
net.inet.carp.preempt
Allow virtual hosts to preempt each other. It
is also used to failover carp interfaces as a
group. When the option is enabled and one of
the carp enabled physical interfaces goes down,
advskew is changed to 240 on all carp interfaces.
THanks!

I noticed that if I reboot a server that is the MASTER, the carp0 on

Yes, it depends of what you have put in 'net.inet.carp.preempt'
if it's net.inet.carp.preempt=0
than the backap will become master and stays that way
and if it's net.inet.carp.preempt=1
then the "real" master will take over the IP address from backup
server when he gets in the OK state
