 Support for monitoring the health of the system and its processes.
 
-* Add support for a `/dev/watchdog` plugin to replace `watchdogd`
-* Integrate system supervisor to optionally reboot the system when a

-* API for processes to register with the watchdog.

+  - Deeper monitoring of a process' main loop by instrumenting
   - If a process is not heard from within its subscribed period time
     reboot system or restart process.
+  - Add client libwdt library, inspired by old Westermo API and the

+  - When a client process (a standard app/daemon instrumented with
+    libwdt calls in its main loop) registers with the watchdog, we raise
+    the RT priority to 98 (just below the kernel watchdog in prio).
+    This to ensure that system monitoring goes before anything else in
