RE: Class definitions - is "_" (underscore) an operator?

Keep in mind that a multi-homed could have interfaces on both of those
networks, causing both classes to be true. It might be interesting to
inspect the output of cfagent -pv to see what IP addresses CFE thinks
are present.

Also, you should be careful on conditional imports -- I've found that
generally only 'hard' classes can be used to drive imports as soft
classes aren't yet defined at parse time.
