If the produced pdmp file is not written in the places where Emacs
looks for it at startup, then it can only be loaded via --dump-file.

If you are talking about _producing_ a dump file, then I think this
discussion is premature, since we don't yet support re-dumping well
enough, and not at all in interactive sessions.  We should postpone
this until we have the known problems fixed, because only then the
various implications will be known.
