IIRC that is limited by BIOS, right? I thought the original problem is some x86 BIOS doesn't understand EFI so they cannot boot. Is there something else prevents from ZFS using EFI labeled disks for boot device? And for the coming zfs root support in new installer, will new installer still create a zfs in a slice rather than the whole device? Now that's somehow disheartening if we still stuck with SMI and slices. ok, I know write-cache can be forced on with format. I also know that practically EFI doesn't bring additional advantage over SMI label for small systems.
