disable systemd coredumps?

Hey,

I do software development. During that, programs segfault, and they do that often. I really do not want something to create a 300 MB core file each time something segfaults. How do I turn that off? I tried setting

[Coredump]
Storage=none

in /etc/systemd/coredump.conf.d/custom.conf, and setting

kernel.core_pattern =

in /etc/sysctl.d/50-no-coredump.conf, but the former did nothing apparently and the latter just makes all the dumps have an empty file name (except for the dot and the PID).

Any ideas?
Greetings,
Sven

Have you tried masking systemd-coredump.socket?

Disclaimer: I haven't tried this, I have no idea if there are any negative consequences beyond stopping the coredump handling.

@op - This should do it:

/etc/systemd/coredump.conf
[Coredump]
Storage=none

OP may have found this in https://wiki.archlinux.org/index.php/Core_dump , so maybe the wiki needs fixing.

This seems to have worked. Thanks a lot!

Re: disable systemd coredumps?

This will prevent the storage of coredumps, but you can disable their generation completely by symlinking /etc/sysctl.d/50-coredump.conf to /dev/null.
