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.
