Comment 15 for bug 2060311

Hi Lukas,
I tested the package in your ppa with following configuration:

```
network:
        ethernets:
            all:
                dhcp4: true
                match:
                    name: e*
                optional: true
        version: 2
```

With the version `1.0-2build1` it hit the timeout even though I set all the interfaces on my DUT(arm64) optional.

Here is the log of journalctl for relevant occurance:
```
Apr 16 11:47:11 kria systemd[1]: Starting systemd-networkd-wait-online.service - Wait for Network to be Configured...
Apr 16 11:49:11 kria systemd-networkd-wait-online[1055]: Timeout occurred while waiting for network connectivity.
Apr 16 11:49:11 kria systemd[1]: systemd-networkd-wait-online.service: Main process exited, code=exited, status=1/FAILURE
Apr 16 11:49:11 kria systemd[1]: systemd-networkd-wait-online.service: Failed with result 'exit-code'.
Apr 16 11:49:11 kria systemd[1]: Failed to start systemd-networkd-wait-online.service - Wait for Network to be Configured.
```

But after installing the version `1.0-2ubuntu1~ppa3`, `systemd-networkd-wait-online` is not triggered since all interfaces set to optional. Therefore no timeout
```
ubuntu@kria:~$ apt policy netplan.io
netplan.io:

```

```
ubuntu@kria:~$ journalctl -u systemd-networkd-wait-online --no-pager -b
-- No entries --
```

It looks like the package you have fixes the issue
