Comment # 1 on bug 1173483 from Thorsten Kukuk

The problem is the following pull request:
https://github.com/SUSE/rebootmgr/pull/3

Richard, do you remember why rebootmgr should not be killed during shutdown? By
looking at the code I see only a log message which could not be printed after
systemctl reboot is called.


What happens here is:
systemctl will not stop rebootmgr during a restart, but starts a second
instance. And the second instance will core dump. While a second instance
should abort with an error and should not crash, the problem is, if systemctl
is not allowed to kill rebootmgr during shutdown, we can never restart it with
systemctl.
