Sorry for the confusion, I meant the problem is not explicitly related to hotplug. Pattern matching, as in the way how you use it, does not work either for "auto" interfaces, as I described in my previous mail. > > You expect that ifupdown matches an interface given as argument to the > > lists of interfaces in auto, allow-hotplug, etc, even without defining > > them, as long as they are known by the kernel. > > That's the whole point of mapping patterns. Yes. I was trying to ACKing the problem you describe. The problem is when you call an ifupdown command for an interface not-explicitly defined but that should match a configured pattern. The behaviour is different when you call e.g. `ifup -a` or `ifup --allow=hotplug -a`
