** Description changed:
+ [SRU Justification]
+ As a hardware diagnostic service, it's important that opal-prd be kept
running even in the face of hardware unreliability. The most effective way to
do this is with a systemd unit policy of Restart=always, to ensure the service
is not allowed to accidentally die.
+
+ [Test case]
+ 1. Install the opal-prd package on a system that has /dev/mtd0.
+ 2. Verify that the service is running with 'systemctl status opal-prd'.
+ 3. Get the pid of the opal-prd process from systemctl and kill it with 'sudo
kill -9 $pid'.
+ 4. Verify via 'systemctl status opal-prd' that the service is no longer
running.
+ 5. Install opal-prd from -proposed.
+ 6. Verify via 'systemctl status opal-prd' that the service is running again.
+ 7. Kill the new process with 'sudo kill -9 $pid'.
+ 8. Verify via 'systemctl status opal-prd' that the service has been restarted.
+ 9. Install the opal-prd package from -proposed on a system that does not have
/dev/mtd0.
+ 10. Verify that 'systemctl status opal-prd' shows the service is inactive,
and has not been allowed to restart indefinitely after failure, driving up the
system load.
+
+ [Regression potential]
+ Since the package may be installed on systems where opal-prd is useless and
will not run, it's important to verify for each release that Restart=always
doesn't cause systemd to go into a busy loop trying to restart the service
under these conditions. The uploaded change should guard against this by
checking for the correct path before starting the job, and the test case should
further confirm this.

+ opal-prd package contains prd daemon (Processor Runtime Diagnostics).
One of the requirements from a field service perspective is to be able
to restart opal-prd when it fails for whatever reason.
Direct systemd to restart the opal-prd service on any kind of failure.
- Ubuntu contains opal-prd package. This bug is to restart daemon after failure
