automatically configuring carp(4)

[Ray Phillips <r.phillips%uq.edu.au@localhost>]

What's the recommended way of configuring carp(4) so it will be 
configured each time a machine starts?  Is it putting the 'ifconfig 
carp0 create' command, etc. in /etc/rc.local, or perhaps creating a 
/etc/ifconfig.carp0 file and adding a

net_interfaces="carp0"

line to /etc/rc.conf ?
