why is /usr/lib/sysctl.d/50-coredump.conf not being consulted?

[Robert P. J. Day]

  i'm sure there's a simple answer to this, but i'm digging around in
systemd-coredump, and while the file
/usr/lib/sysctl.d/50-coredump.conf contains:

kernel.core_pattern=|/usr/lib/systemd/systemd-coredump %p %u %g %s %t %e

the file /proc/sys/kernel/core_pattern still contains:

|/usr/libexec/abrt-hook-ccpp %s %c %p %u %g %t %P %I

am i missing something here? is there a precedence/ordering issue, or
have i forgotten to start some relevant systemd service?

You've probably started too many services :-). I think that
both systemd and all the "abrt" stuff have dueling core patterns
(with possibly the abrt stuff setting the file dynamically
rather than from any .conf file that can be discovered).
