First off, as of 10.1-RELEASE FreeBSD cannot boot from a ZFS root partition via UEFI. It's simply not possible right now. Second, my T520 will only boot FreeBSD from a GPT disk via UEFI, and the T420 likely has the same firmware. So you can format an MBR disk with ZFS and boot via legacy mode, but ZFS can't boot from GPT with UEFI. Or you can do what I did, and create a 1.5G partition for the root ('/') filesystem, format it to UFS, and leave the rest of the disk for ZFS. - Bigby -- "A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools." - Douglas Adams
