Does zfs/zpool support the layered driver interface? I wrote a layered driver with a ramdisk device as the underlying device, and successfully got a UFS file system on the ramdisk to boot via the layered device.
I am trying to do the same with a ZFS file system. However, since ZFS file systems are created as datasets within a storage pool and not directly on a specified underlying device, I can't think how I will get a ZFS file system to mount using a layered driver atop a real device. I tried specifying the layered device as the storage pool component for 'zpool create', but that gave me an "invalid argument for this pool operation" error. I also tried setting the mountpoint for a zfs filesystem as 'legacy' and doing a regular mount with the layered device, but that gave me an "invalid dataset" error. I looked through the documentation for zfs/zpool and searched extensively, but haven't been able to figure this one out yet. I am a newbie to ZFS, so pardon me if this is something trivial. Can someone point me to possible method to achieve the above?
