/etc/netplan/50-cloud-init.yaml too specific

[Heinrich Schuchardt]

When installing a virtual machine with the live-installer it created /etc/netplan/50-cloud-init.yaml with

network:
    ethernets:
        enp0s6:
            dhcp4: true
    version: 2

When I rebooted I had a device enp0s4 and no network.

Wouldn't it be preferable to write a less restrictive 50-cloud-init.yaml which encompasses all Ethernet devices and marks them as optional:

network:
    version: 2
    ethernets:
        all-en:
            match:
                name: "en*"
            dhcp4: true
            optional: true
