It seems that zfsboot requires the freebsd-zfs partition to be the first, so make sure you add if first, before your swap partition.

Re: ZFS on MBR does not boot at all
I had to set up ZFS on MBR lately. Since I'm lazy I wrote a script for that. Maybe it would suit your needs (it's very simple though). https://bitbucket.org/ukaszg/freebsd-zfs-on-mbr-installer 2013/5/9 Giorgos Keramidas keram...@ceid.upatras.gr: On Sun, 05 May 2013 17:56:49 -0500, Joshua Isom jri...@gmail.com wrote: On 5/5/2013 3:20 PM, Giorgos Keramidas wrote: Hi David, Thanks for following up with what the real problem was.
