Such as Etherboot.  I have noticed that in -stable for root to be
set right with PXE I need to pass in vfs.root.mountfrom with the nfs 
root.  I have a patche to stable that sets it in pxeboot.  The caveat is
that this would force people to have to do a
	vfs.root.mountfrom=ufs:/dev/md0a
in loader.conf to make the install floppies work via PXE.
