Details

Here is my setup. ifplugd is managing the wired interface as eth0, and I have a wifi card using the airo module that is being managed manually and is eth1. If I bring up both interfaces, everything is fine, 'route' shows a default route for both interfaces. If I unplug the wired interface, ifplugd takes out the default route for both interfaces, and I obviously can no longer reach beyond the local network. Both default routes are restored when the wire is plugged back in. I have only eth0 specified in /etc/ifplugd/ifplugd.conf as the interface to manage.

I don't know if this is a configuration issue with ifplugd, an issue with how the network scripts operate, or something else, but on every other distro I have used, ifplugd only takes down the stuff associated with the managed interface, so there is something about Arch that causes this behavior.
This task depends upon

Well, here is the offending code:

case "$2" in
up)
ifup $1
# ugly way to load up gateway, since
# al's net configuration doesn't associate
# gateways with specific interfaces
/sbin/route add $gateway
;;
down)
ifdown $1
# same as up...
/sbin/route del $gateway
;;
*)
echo "Wrong arguments" > /dev/stderr
;;
esac

Is it not possible to take down a gateway based on the device/interface being taken down?

Sorry, that code snippett is from /etc/ifplugd/ifplugd.action

okay, this is easily solved by changing

/sbin/route del $gateway

to

/sbin/route del $1

everything works as expected here after making that very small change. Only the default route for the interface being managed is deleted then.
