Hi all,

i was wondering if there is any ready-made method to trigger an action as soon as a link changes state.
Along the lines of
        onifdown_em0="/run/this/script"
in rc.conf

Background:
Discussing physical data security with a client yesterday: The machine has to run 24/7. The filesystem is encrypted on boot, but this doesn't help a lot if anybody brings an AC generator to steal the machine *AND* the UPS. Best point in time to lock the machine I could think of was when somebody pulls the NIC cable.

Regards,

Michael
