So if you suspect ZFS it might really be an option to replace gptzfsboot with gptboot. I recently changed the configuration of my home server from 1x80GiB SATA HDD (booting & /-pool) and 4x400GiB PATA HDD for zraid-Pool on geli to 2x2TiB SATA HDD with gmirrored /boot and the rest for a geli encrypted zmirror (including /). For me it feels as if it takes a few seconds longer for the loader to appear. The latter uses GPT and labels where possible. HTH Christian
