# Simple ifstated config file.  Assumes at least one carp interface
# (carp0).  When ifstated starts up, it'll switch to the proper state
# depending on whether or not your host is the current carp master.  When
# it hops between states, it'll email you and tell you.  
#
# Warning, if things really go south, you may get barraged with emails as
# the carp master and slave bounce back and forth.  Be careful!
