As long as there was a switch there or query there to force a newfs,
if desired.  Sometimes, I really do want to blow away anything previous,
as cleanly as I can, after botched installs, bad crashes, system burps,
admin stupidities, changing flavors of OS, etc.  IF newfs did not, then
that would leave a llfmt as the only recourse.
