Since anacron jobs were replaced with timers, I am seeing a noticeable delay before agetty prompt appears on machines which were unused for some time (due to update/man-db timers starting up simultaneously).
TLDR: Anacron inserts a random delay between boot and running the jobs, so is it possible to simulate this behavior by including e.g. "OnBootSec=..." in the timers at next update? Or is this option incompatible with OnCalendar?
OnBootSec would cause the timers to always run on boot, no matter how much time has passed, which is not what we want.
I don't think it is a problem that the timers run on boot, but rather that they delay Type=idle units, like agetty. From what the documentation says, there should not be any delay:
"Behavior of idle is very similar to simple; however, actual execution of the service binary is delayed until all jobs are dispatched."
I am confused why get a delay here.
I think another solution in systemd would be introducing a holdoff time: Instead of running immediately on boot, the timer should be scheduled for boot+5min.
This requires some investigation - sorry, I don't have a quick solution right now.
