We just want all the 246x systems to go away.  When the hardware doesn't
break, we've got the cluster set up so that it will boot and run
reasonably well (the systems are, or were, very admirable performers
numerically).  At this point, it is human interaction and human time
wasted on hardware problems that are the real expense.  If it weren't
opportunity cost time vs money we don't have, we would have thrown the
entire cluster away long ago and replaced it.
