Systat (singular) may need recompilation.  I changed DK_NDRIVE to
eight, not wanting to bother finding any `char's holding bits in
the range [0..DK_NDRIVE), and not having more than six disks on
any one machinge.  After all our local changes were installed, I
did a `cd /usr/src; make clean; make depend; make; make install'.
Beware!  This takes at least eighteen hours on an otherwise unloaded
750.  (Actually, I made all the libraries first, and installed
those, then did a full make.  It took three days to straighten out
all the little errors along the way.)
