I also noticed this bug recently. I find it very annoying to get system emails now whenever unattended-upgrades is scheduling a reboot. It should either be fixed in systemd (why are they writing an info message to stderr?) - or if it can't be fixed there, at least unattended- upgrades should redirect the output of the shutdown command to avoid these messages.

This causes unattended-upgrades to run: '/sbin/shutdown -r +5' Systemd's shutdown writes an acknowledgement message to stderr: Shutdown scheduled for Wed 2016-05-18 04:37:49 BST, use 'shutdown -c' to cancel. Which cron picks up and emails - but I don't really want to know. Is there any scope for unattended-upgrades to gobble shutdown's stderr message? Or, perhaps this should be logged against systemd, since the shutdown message isn't really an obvious candidate for stderr?
