Your gist helped me, ty.
Can you correct this : gmirror label -v p1 /dev/da0p1 => ada0p1 ;
and precise "After the installation, replace /mnt/boot with /boot2 in /etc/fstab ", because I was very confused by this line and failed the installation many times because of this, and I think it may help other people :)
