Hello,
Fwiw, this behaviour makes sense to me.
If you start a scheduled login 2 days in advance, sending a shutdown
message every minute would not be helpful. Restricting that to the last
ten minutes seems reasonable.
How did sysvinit behave in that regard?
As far as I remember, sysvinit started earlier with showing messages,
but the interval between the shutdown messages became shorter the closer
the actual shutdown time came, every minute in the last ten minutes,
five minutes with current_time < shutdown_time - 10 minutes, even longer
intervals with current_time << shutdown_time - 10 minutes.
Regards
Christoph
