From: Nickle Wang via groups.io @ 2023-11-23 14:33 UTC (permalink / raw)
  To: devel; +Cc: Abner Chang, Igor Kulchytskyy, Nick Ramirez

-Fix typo (replace Listheader to ListHeader).
-Replace "%a," to "%a:".
-Add more debug message.
-Remove the exit-boot-service event and use after-provisioning
event to save ETag data. Variable may not be writable during
exit-boot-service callback.
