Nope. 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.
