Oooops, too fast.

I wrote this script:

#!/bin/sh

echo "Param1 = '${1}'" >> /root/log
echo "Param2 = '${2}'" >> /root/log

And added this action on devd config:

notify 0 {
         match "system"          "IFNET";
         match "type"            "LINK_UP";
         media-type              "ethernet";
	action "/root/log.sh -c 'interface linkup start '$subsystem";
};

notify 0 {
         match "system"          "IFNET";
	match "type"            "LINK_DOWN";
	media-type              "ethernet";
	action "/root/log.sh -c 'interface linkup stop '$subsystem";
};

And got the following output on /root/log:

Param1 = '-c'
Param2 = 'interface linkup start $em0'
