Following the instructions in issue [#659](https://github.com/systemd/systemd/issues/659) and reading `man systemd-coredump(8)`, that means, masking the file with `sudo ln -sf /dev/null /etc/sysctl.d/50-coredump.conf`, even after `systemctl restart systemd-sysctl`, it has no effect on the running system, and requires a reboot. The reason is, that the key `kernel.core_pattern` is now not mentioned, and therefore left on the setting from the current boot. The command below has to be manually run to avoid a system restart. sudo sysctl -w 'kernel.core_pattern=|/bin/false' Is there another way to disable systemd-coredump on the running system?
