ACL Passthrough with Mode Preservation Deferred Update

With this deferred update, there is improved interoperability between ZFS, NFS, and SMB sharing. Previous versions of software allowed five options for this setting: discard, noallow, restricted, passthrough, and passthrough-x. Release OS8.6.0 introduces the option passthrough-mode-preserve.

This option allows inheritable ACL entries to be inherited, while preserving the creation mode specified by the application. This preserves the inheritance properties so SMB creates ACLs that interoperate with shares accessed over NFS and SMB simultaneously.

If this deferred update is not applied and you use the passthrough-mode-preserve option in the CLI, an error appears indicates that the deferred update needs to be applied. In the BUI, this option will be grayed out and cannot be selected. A project or share with this option set can only be replicated to a target with the same deferred update applied.
