No more coredumps after migrating to systemd

Generating coredumps used to work fine, but after switching over to systemd, I only see the message Aborted (core dumped) but no core file is generated. Has it something to do with systemd? (Background: My original question can be found here . Thanks schaiba for finding the solution. I provide this Q&A, so others can find the solution easier if they already know that it is a systemd issue.)
