I thought this was something we covered in the noble cycle's rework of
wait-online.
@lukas, isn't this the purpose of:
[Unit]
ConditionPathIsSymbolicLink=/run/systemd/generator/network-online.target.wants/systemd-networkd-wait-online.service
netplan should only create that symlink if it generates a valid config?
If not, the symlink won't be present, and then the unit would be
skipped.
That's obviously *not* working here, but I thought those were the
desired semantics.

Title:
Offline install results in empty /etc/netplan, which stalls boot for

Bug description:
I did an offline install of plucky 25.04 server on a laptop. I
unplugged the network cable, and didn't configure wifi.
The installation finished, but first boot, and subsequent boots, were
delayed by 2min+, waiting on systemd-networkd-wait-online.service.
Further inspection showed that /etc/netplan was completely empty. Not
surprising to me, as no network was configured during installation,
but having the system still waiting for a network in this case was
surprising.
Creating the following file in /etc/netplan made boot fast again:
$ cat /etc/netplan/01.yaml
network:
version: 2
ethernets:
<nic-name>:
optional: true
This looks similar to
https://bugs.launchpad.net/subiquity/+bug/2063331, but I opted to file
a new bug because that one is "fix committed", and the user did
configure one nic at least in that bug.
