service examples: if iface do not exist, retry upping it
I've had a case of a machine where eth0 was appearing a bit later after the boot, and appearing _downed_. ifplugd then fails to detect "link up". Thus, depending on how service startup ("ip link set dev eth0 up") races with driver initialization, ethernet randomly fails to initialize on boot.
