This should probably be /run/reboot-required, /var/run is a symlink to /run.

That said, an update of the systemd package does not strictly require a
reboot of the system. We do reexec PID 1 and restart all binaries
(besides logind), so I'm a bit undecided if we should actually trigger
that message or not.

Why is it that all of the instruments seeking intelligent life in the
universe are pointed away from Earth?
