This is printed by bus_manager_log_shutdown() in logind-dbus.c,
near the start of the shutdown process.
Clarify that events *will* happen, long after this message is sent.
This message appears when a computer hibernates, then awakens, then reboots,
and everything goes OK. It's a normal progress message the user doesn't need
to know about, but it distracts them from important startup messages and could
even train them to ignore the warning when the procedure fails.
Reduce the level to LOG_INFO.
The "vice versa" in the old text could be interpreted as either
(wrong) "stopping the former will start the latter", or
(right) "starting the latter will stop the former".
Rephrase to avoid that ambiguity.
The documentation for `RestartPreventExitStatus=` differs from that for `SuccessExitStatus=` in ways that are sometimes confusing (e.g. using `numeric exit codes` instead of `numeric termination statuses`), and other times plain incorrect (e.g. not mentioning `termination status names`, which I've just confirmed to work in systemd 255).
This patch modifies the documentation to be as similar as possible, so as to reduce the reader's cognitive load.
