you have to override vfs.root.mountfrom in the hypervisor's loader
bhyveload. otherwise it looks at /etc/fstab in the root filesystem,
and you can't have it work both ways..

one possibility is to use  gpart label to describe the device.
possibly it woudl hav ehte same result in both cases, but I don't know 
for sure that
it works for root device.. you'd have to test.
