Yup, and this is an advantage. On the other hand, if you tie the
device name to the slot number (the real goal), you can swap different
hardware into that slot without having to modify any configuration
information at all.

It wouldn't be too difficult to extend the configuration to allow entries like this:

Interface0_addr="MAC 01:23:45:67:89:ab"
Interface1_addr="PCI 0:1:2" # pci0, device 1, function 2
Interface2_addr="USB 0:1:2" # usb0, addr 1, port 2

Add some bits to grok dmesg or pciconf/usbdevs or maybe even trigger from devd and there you go.

I should mention that the second and third options could be broken by the addition or removal of a card with a PCI bridge or USB root hub on it.

Of course, this doesn't help the OP's problem of wanting to be able to
address the sole interface in a system without knowing it's name in
advance. Maybe a feature to provide a default name for an interface if
one isn't found in the config file would do that.

# ifconfig `ifconfig -l link` name GenericName
