It goes on to say:
For backward compatibility, if /proc/sys/kernel/core_pattern
does not include %p and /proc/sys/kernel/core_uses_pid (see below)
is nonzero, then .PID will be appended to the core filename.
This is core(5) for the record. "man core" may bring up other pages
depending on what's installed.
