I'm all for it! I've just spent an hour trying to test out an init.d script,
but it is not very robust without a pidfile, so your patch would make things
so much easier...
Emacs does have the (emacs-pid) lisp function, but that too is not easy to
try, and there may be race conditions when two --daemons are started.
Actually... with your patch, if two emacs --daemon --pidfile=same_file are
started, what will happen?
