Add a cross mount feature to NFSv3
Currently NFSv3 on ON/Net does not support cross mounts. If this feature were available it would remove administrative issues and mount limitations when using a VMware NFS client as a storage consumer of ZFS. As it stands today if a customer would like to use ZFS clones as a provisioning method they must create separate fs mounts for each clone instance and this is also encumbered by a 64 mount limit. By engaging the NFS client to server cross mount functions the VMware NFS client is cleared of it's issues and customers will immediately have access to the most efficient VDI provisioning platform in the world.
