It is no offense just if someone could give hint if e.g. UEFI works with GPT and gptzfsboot works with GPT why efi loader cannot utilize code from gtpzfsboot to use zfs boot fs directly. Also if not now approximately when it will support zfs? Or there are so many obstacles on road rather makes mid term workaround to use efi + zfs-root-ufs-boot combo? Thanks.
