AWS AWSCloudFormation documentation change
Summary
Changed documentation from ECS TaskDefinition InferenceAccelerator to FSx S3AccessPointAttachment OpenZFSFileSystemIdentity. Updated properties to specify POSIX user identity for file access authorization.
Security assessment
The change introduces documentation about file system user identity configuration for S3 access authorization, which relates to access control security mechanisms. However, there is no evidence of addressing a specific security vulnerability - this appears to be standard documentation for a security-related feature (access authorization) rather than a security fix.
