Michael, as to what the bug report is about I guess there are three issues:
1) At some point the /etc/systemd/system/sshd.service file has been updated to include RestartPreventExitStatus=255 which has a negative effect stopping sshd restarting in order to work with a slow to start network connection. This does not seem to be a sensible default option. I don't know if this comes under sshd or systemd. 2) The override.conf mechanism does not seem to be working. Which is a definite systemd issue 3) systemd seems to be complaining about the need to reload units using daemon-reload even when you have just done daemon-reload These seem to have come in with the last point release, and as of yesterday, the latest updates on top of that had not addressed these issues.
