The new systemd version v252 brings a new naming scheme, in particular it seems that on device tree based systems (e.g. Raspberry Pis) the Ethernet device name changes from eth0 to end0. This breaks a previously made configuration. Even worse, it seems that the default NetworkManager behavior is to only configure a network device if there is no profile. But since profiles are configured on a typical installation, NetworkManager doesn't bring up any of the network interface, leaving the user stranded on an unconnected system. Ideally, we should have a plan how to migrate from one naming scheme to the next. For now, just stick with the naming scheme HAOS 9.x has been using.
