</span>Specifically, if the first character of core_pattern is '!', the rest<br>
should be an executable, to which the core file is handled. IIRC Centos7<br>
had something of that type installed by default. On Debian Stable you<br>
have the package corekeeper (or maybe also systemd-coredump from<br>
backports). I haven't tried any of those.<br>
