<p class="MsoNormal">I recognize that it is a slight change of the experiment to remove upsdrvctl, but could you please start the driver directly in the init script with -DDD (path should be in the output of '/usr/sbin/upsdrvctl -D'), and redirect that output
to a log file? (We had a reason for why upsdrvctl does not pass '-D' flags through to the driver, but the reason escapes me at the moment.)<o:p></o:p></p>

RFC: we should probably consider for upsdrvctl that -D... is passed to the driver(s) and -d... for upsdrvctl specifics.<o:p></o:p></p>
