IIUC these options actually aren't mutually exclusive. We can easily provide a single `(t)emacs` executable which at startup will: - look for a valid dump in the big static `dump` array. - if not found look for a valid dump in a particular ELF section. - if not found, look for a valid dump at the end of the `emacs` binary. - if not found, look for a dump as a separate file at some standard location (starting with ~/.emacs.d/.dump, say). - as support a "--preload .dump" command-line option.
