** 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. + 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 changes the systemd config to ensure systemd-networkd.service is included as an active service whenever multi-user.target is wanted (which is the default) instead of only when network-online.target is wanted, since the latter is optional and on some installations is not required at all. This does not change the ordering of boot at all since in both cases systemd-networkd.service is correctly Before=network.target, and it is Before/After, not Wants/Requires, that determines ordering. --- 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.
