 ## Support in the Service Manager (PID 1)
 
 The systemd service manager natively provides coredump handling functionality,
-as implemented by the Linux kernel. Specifically, PID 1 provides the following

 2. At the same time it will turn off coredump handling in the kernel by writing
    `|/bin/false` into `/proc/sys/kernel/core_pattern` (also known as the
    "`kernel.core_pattern` sysctl"; see
    [core(5)](https://man7.org/linux/man-pages/man5/core.5.html) for

 Net effect: after PID1 has started and performed this setup coredumps are
 disabled, but by means of the the `kernel.core_pattern` sysctl rather than by

 With the above, any coredumps generated on the system are by default collected

 ## Alternative Coredump Handlers
 
 While we recommend usage of the `systemd-coredump` handler, it's fully
-supported to use alternative coredump handlers instead. A similar
