Subject: [PATCH] Do not fail a finished install over the monitoring service

The last step restarts ping-instances.service when the host has it. On
hosts whose unit file systemd rejects ("bad unit file setting") that
start failed under the ERR trap, and 14 installs that had completed were
reported as failed. It is a warning now.
