** Description changed:
+ [Impact]
+ Minimal installs using netplan to configure the network.
+
+ [Test case]
+ 1) Install Ubuntu minimal server / cloud image
+ 2) Edit /etc/netplan/01-netcfg.yaml to configure the network as necessary.
+ 3) Run 'sudo netplan apply'. Verify that the network comes up correctly.
+ 4) Reboot.
+ 5) Verify that the network comes up properly.
+
+ [Regression potential]
+ Minimal; this reverts changes in a package that was never released to
-updates, only available as SRU in -proposed and on the devel release. This
only applies to the order in which systemd-networkd is enabled when used as a
renderer for netplan configuration, to start in multi-user.target instead of
the "correct", but inefficient "network-online.target" as the latter may not be
depended upon in minimal installs.

After doing a default disco installation on s390x using the beta ISO image
aka daily from March 26th and the post-install reboot the system restarts aka
reipls (in z/VM in this case) but the interface is not brought up.
Hence no remote connections are possible.
The ip cmd shows:
- ip a
+ ip a

The netplan yaml file looks fine:

+ cat /etc/netplan/*.yaml

- # For more information, see netplan(5).

Using ip to bring the interface up doesn't help:
buntu§hwe0007:ß$ sudo ip link set enc600 up
sudo ip link set enc600 up

(Sorry for the partly duplicate lines and some strange characters, but
this is due to the fact that I copied the output from the console that
requires a 3270 terminal emulation)
