Well, do you mean I must update my shutdown script whenever I install
something new just because this "something new" does not like
standard, well accepted method of signalling apps to exit?

Why not make portmapper+NFS daemons killable by TERM, giving them
the chance to do proper cleanups rather than abrupt KILL?
