What minetest modification caused the server failure? How can we
reproduce the data inconsistency?

Restarting the server is equivalent with stopping and starting the
server again. Systemd will send a SIGTERM signal by default to the
server to terminate the running process. I don't see a reason why we
should use a different KillSignal in this case. SIGINT means
interrupting the process.

I suggest to investigate the cause of the server failure and then report
your findings to the mod developers. If they think it is rather a
minetest bug, please get in contact with the minetest developers
directly because this is the fastest way to get your issue solved.

If you want to play with different service file settings, use a modified
service file in /etc/systemd/system to override Debian's default settings.

Regards,

Markus
