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.

Understanding Deferred Updates

Each update may come with new firmware or updates to external resources. In general, these
updates are backward compatible and applied automatically without user intervention. There
are exceptions, however, for non-reversible updates. These updates involve updating a resource
external to the system software in a way that is incompatible with older software releases.
Once the update is applied, rolling back to previous versions will result in undefined behavior.
For these updates, you will always be given an explicit option of applying them automatically
