The operating system has also been successfully updated to the latest available version to validate the persistence and compatibility of Docker post-update.

How Has This Been Tested?

1. Multiple variants of EMT images—RT, Non-RT, Dev RT, and Dev Non-RT—have been successfully built with the applied patch.
2. Each image has been tested to ensure that Docker remains functional and its state is preserved after performing a system update using the OS Update Tool.
