I'm trying to build a bootable ZFS system on a USB drive. Using the procedure below results in the following error when I try to boot:

        gptzfsboot: error 66 LBA 48
        gptzfsboot: error 66 LBA 1
        gptzfsboot: No ZFS pools located, can't boot

Presumably gptzfsboot relies on the BIOS mapping the USB device into a DOS device. Do you have that support turned on in the BIOS?

I was testing this on a 2010 vintage HP G71 laptop which has no BIOS settings for USB. I didn't think about it being a BIOS issue since it boots gptboot/UFS with no problem. So I tried booting the very same gptzfsboot/ZFS USB drive on a different machine and it boots fine, so I guess it is just a HP BIOS problem. Sorry for the false alarm.
