 * Ethernet devices: `eth[N]`, where 0 ≤ N (`eth0`, `eth1`, ...) This naming

 release. When upgrading to 5.0, the names are kept as-is.

 Do not forget to adjust `/etc/network/interfaces` to use the new name.
 You need to reboot the node for the change to take effect.
 
-NOTE: It is recommended to assign a name starting with `en` or `eth` so that
-{pve} recognizes the interface as a physical network device which can then be

-with other interface names in the future. One possibility is to assign a name
-that does not match any name pattern that systemd uses for network interfaces
-(xref:systemd_network_interface_names[see above]), such as `enwan0` in the
