+              hash: 7146e4614c2658d6f7d5384602eb8ad213e08759
+              body: >
+                Previously, our healthcheck verified if we were able to start a
+                new
+
+                container. This had two downsides:
+
+
+                1. It was relatively heavyweight. In devices under heavy load, it would
+                   sometimes take so long to run that the Engine was killed by the
+                   watchdog.
+                2. It wrote to the storage media. Creating a container involves writing
+                   some data to persistent storage, therefore the healthcheck was
+                   wearing the storage media.
+
+                This new healthcheck simply pings both `balenad` and `containerd`, which
+
+                is much faster than starting a new container and doesn't write to disk.
+
+                The step of pinging `containerd` is important because we have seen at
+
+                least one case in the past in which `balenad` was working but
+
+                `containerd` wasn't.

+              hash: 9e322ee25bf50949880446f4fb85d1d8e864da37
+              body: >
+                With `WatchdogSignal=SIGTERM` systemd will send a SIGTERM and
+                give the
+
+                Engine 90 seconds to gracefully shutdown before sending a SIGKILL. We
+
+                had cases of Engine metadata on disk getting corrupted after the
+
+                watchdog sent it a SIGKILL directly. This change shall minimize this
+
+                issue.
