[systemd-devel] Inherit MAC address for bridge from physical device

[Olaf Hering]

With ifcfg or NetworkManager it is possible to have generic config files for every system to configure a bridge on the one and only physical network interface. See the examples below how such configuration looks like.

With systemd-networkd it is apparently required to specify the MAC in the configuration. As a result, such configuration is per host and not generic anymore. Is there a knob I overlooked so that the bridge uses the MAC from the physical interface? If not, are there plans to fix that?
