Okay, that worked.  I didn't really understand what was
in my /proc/sys/kernel/core_pattern previously.  I think
it started with a vertical bar -- |.

I didn't do the
echo '1' > /proc/sys/fs/suid_dumpable

yet, but may need it for the next steps.  I've just
tested it with that little script and will work on
this with my server next.
