             Bug #: 54288
           Summary: there should be an easy-to-find way of extracting
                    coredumps, or the coredump hook should default to off
    Classification: Unclassified
           Product: systemd
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
        AssignedTo: systemd-bugs at lists.freedesktop.org

systemd-189 seems to be installing its coredump hook
(/usr/lib/sysctl.d/coredump.conf, running systemd-coredump) by default, but
this seems to eat all coredumps with no obvious way to get them back out into a
form you can run tools like gdb on. If there is such a way: please point me at
it and consider improving the documentation (I looked mainly in "man
journalctl", after checking if systemd-coredump has its own manpage, which it
somewhat understandably does not). If there is no such thing yet: please
consider disabling the coredump hook until one exists, unless there are
non-obvious advantages to having coredumps stored in the journal that outweigh
the frustration of not finding coredumps anywhere until you remember the
existence of the kernel.core_pattern sysctl and turn this integration off.

All this is with systemd-189 (various older versions have the same problem).
