Yes, /lib/udev/net.agent. It calls ifup or ifdown if the interface is
configured in /etc/network/interfaces, i. e. with ifupdown. But if it
does not appear in "ifquery -l" the script doesn't touch the
interface.

To be 100% sure you can temporarily move away /lib/udev/net.agent and
see if it still happens?

Thanks,

Martin
