Bug#871490: mention how to force listing of /var/lib/systemd/coredump

[積丹尼 Dan Jacobson]

Package: systemd-coredump
Version: 234-2
Severity: wishlist
File: /usr/share/man/man1/coredumpctl.1.gz

Man page says

           It's worth noting that different restrictions apply to data saved
           in the journal and core dump files saved in
           /var/lib/systemd/coredump, see overview in systemd-coredump(8).
           Thus it may very well happen that a particular core dump is still
           listed in the journal while its corresponding core dump file has
           already been removed.


OK, but do mention how to make it list these three coredumps.

# coredumpctl
No coredumps found.
# coredumpctl -D /var/lib/systemd/coredump/ list
No journal files were found.
No coredumps found.
# ls -l /var/lib/systemd/coredump/
