   The service api is designed in such a way that it expects an empty list for match all. And it sends back an empty list in the response every time. Hence this behaviour from terraform side. This can be safely ignored.

-### Modification Process
-- When there is a change to any of the instance parameters, the volume policy assignment will get recreated. Example: If you want to add a NSG to the instance, you will be notified on a read to the boot volume ocids, modification to the instance and, a create and destruction of the policy assignment. Screenshot below for reference. This behaviour is expected and in order to not have the backup policy recreated, comment the depends_on statement in modules/compute/data.tf at line around 35.

+- If the description field is having any newlines in the tenancy then the export of the compoennt and tf synch will show output similair to below:

+ This is how terraform handles newlines in the fields. Pleage ignore this and proceed with terraform apply.
