it took a good deal of effort to validate this, beyond what's in the test case, because it turns out that there are no units in the default desktop install at all that pull in network-online.target; so I had to create /etc/rc.local and modify /lib/systemd/system/rc- local.service.d/debian.conf to include 'Wants=network-online.target' see anything worth looking at (and the latter is probably also a bug in that unit). But ultimately, I've managed to get to the following state:

I believe that users who have continuously upgraded their systems, including over pre-releases of Ubuntu, may have been left in the same situation, where NetworkManager-wait-online.service is inactive and their boot order is therefore unreliable. This disabled NetworkManager-wait-online due to lack of upgrade fix-up may explain other bug reports I've seen around NFS handling, where users continue to report that NFS is not correctly mounted at boot. Though late, a one-time upgrade fix-up is warranted so that users can have consistent handling of the network-online target. [Test case] 1. On an affected system, run 'systemctl status NetworkManager-wait-online'. Observe that the unit is listed as disabled. 2. Install network-manager from -proposed. 3. Run 'systemctl status NetworkManager-wait-online' again and verify that the unit is no longer marked as disabled. 4. Reboot and verify that the system still boots correctly. [Regression potential] Since NetworkManager-wait-online uses a 30 second timeout, services that depend on network-online.target should see at most a 30 second delay in startup. There should be no functional regressions, only regressions in the speed of boot and only on systems where services have explicitly declared that they depend on the network and the network is not available at boot.
