-- | The proposed access control configuration for an Amazon EFS file system.
-- You can propose a configuration for a new Amazon EFS file system or an
-- existing Amazon EFS file system that you own by specifying the Amazon
-- EFS policy. For more information, see
-- <https://docs.aws.amazon.com/efs/latest/ug/using-fs.html Using file systems in Amazon EFS>.
--
-- -   If the configuration is for an existing Amazon EFS file system and
--     you do not specify the Amazon EFS policy, then the access preview
--     uses the existing Amazon EFS policy for the file system.
--
-- -   If the access preview is for a new resource and you do not specify
--     the policy, then the access preview assumes an Amazon EFS file
--     system without a policy.
--
-- -   To propose deletion of an existing Amazon EFS file system policy,
--     you can specify an empty string for the Amazon EFS policy.
