Previously, systemd.network.links was only respected with networkd enabled, but it's really udev taking care of links, no matter if networkd is enabled or not. With our module fixed, there's no need to manually manage the text file anymore. This was originally applied in3d1079a20d, but was reverted due to1115959a8dcausing evaluation errors on hydra.
