Create a user # useradd user 2. Switch to user and set limit # su - user $ ulimit -s 256 3. Execute journalctl command $ journalctl Actual results: Segmentation fault Expected results: " Hint: You are currently not seeing messages from other users and the system. Users in the 'systemd-journal' group can see all messages. Pass -q to turn off this notice. No journal files were opened due to insufficient permissions. "
