I deleted everything from /var/configuration/ rebooted, and added some
debug to dig into the specific template replacement:
Aug 09 18:51:47 semitruck entity-manager[2700]: strPtr value:
'$BOARD_MANUFACTURER'
Aug 09 18:51:47 semitruck entity-manager[2700]: templateName:
$BOARD_MANUFACTURER, find: true
Aug 09 18:51:47 semitruck entity-manager[2700]: keyPair.value(): "Inventec"
Aug 09 18:51:47 semitruck entity-manager[2700]: strPtr value:
'$BOARD_PRODUCT_NAME'
Aug 09 18:51:47 semitruck entity-manager[2700]: templateName:
$BOARD_PRODUCT_NAME, find: true
Aug 09 18:51:47 semitruck entity-manager[2700]: keyPair.value(): "Altie"
