I don't know of any exact howto, but the general principles are laid out

It shows how to load geom modules from usb stick, once they are loaded you
can then setup geom,  Next fdisk/gpart accordingly(don't forget to make it
bootable).  If your setup if GPT compatible, I recommend using it.  IMO,
it's significantly more straightforward than the old mbr style.  once you've
got your partitions setup the way you want, create your filesystems and use
the instrustions on the page to extract the distrobution on to them.
Obviously they need to be mounted for this to occur, so adapt the example to
your own use.

Note, I've never tried to boot from a gjournaled geom, but I think it will
