I was looking at the ifconfig output and it certainly could be parsed
for the CARP status I suppose, but it just seemed a little crude and I
wanted to make sure I was not missing something more obvious. Do you
know if the CARP interface is up, available, and stable by the time
/usr/local/etc/rc.d scripts are run?
