I tested it breifly this morning by bringing down fxp0, and it seemed to
work as expected, but I was loged in using ssh, so I shot myself in the
foot :-)
So, this leaves 2 questions.
1. The docs say that bringing down the carp interface, should force a
failover, is this wrong?
2. If I want to hook in other things (eg mail) on failover, should I build
and usef ifstaed, or is there a better way?
Thansk for the help!
