Ok, now the puzzle is how much work to get from a stock FreeBSD .iso
image to something that works with this.  Obviously we need a non-stock
/boot/loader.conf file, or to type some commands manually at a loader
prompt.  I believe the stock GENERIC kernel has the md_root support
for this already, so it may not be that hard to do.
