I don't need to do that. At the moment, it looks possible that I will be moving from a Supermicro server to a Dell. I'm hoping to be able to boot FBSD using the virtual disk on the Dell, configure the hard drives, and then use ZFS send/recv to replicate one server to the other. It's unclear if the data center will provide me with the necessary access. Fingers crossed. I always put the 'boot laoder stuff' on all the disks in the mirror, so the machine can always boot.
