As we know, with systemd, core dumps don't just get written to the current directory but to some obscure journal. Now, I'm a poor old non-root user on some machine, and - I want my core dumps! I can't follow the suggestions to edit files in /etc or run systemd utilities as root. Can I still get my core dump files somehow?PS - If it matters, I'm on Fedora 22.
How can a poor old non-root user get the core dumps systemd ate?
systemd;not root user;core dump
Use systemd's coredumpctl to list and retrieve your core dumps. Use the PID or name of the program to select one to dump (to file -o ...) or to run gdb on.$ coredumpctl listTIME                            PID   UID   GID SIG PRESENT EXEMon 2016-04-11 11:18:23 CEST  21538  1000  1000  11 * /usr/bin/sleep$ coredumpctl info 21538           PID: 21538 (sleep)           UID: 1000 (meuh)           ...$ coredumpctl -o core dump sleep$ coredumpctl gdb 21538(Some intermediate versions of systemd use the name systemd-coredumpctl).Your userid must be in group systemd-journal to be able to do this without becoming root.
