[systemd-devel] systemctl reboot get terminated by signal 15

[Pengpeng Sun]

Hi Lennart,

The issue reproduced at 2021-04-22T15:45:30.230Z,  I ran 'sudo journalctl -b', the log began at Apr 22 15:45:48 which is later than the issue reproduced.
How can I get more early and detailed systemd log?

    That looks like the debug log of systemctl on the client side? I was
    more interested int the logs of systemd, i.e. of PID 1.
