Where? in emacs.c:main, look for: if (argmatch (argv, argc, "-daemon", "--daemon", 5, NULL, &skip_args)) { #ifndef DOS_NT pid_t f = fork (); Why? - mainly because I never thought about the emacs --daemon && emacsclient use-case. - in order to not make detaching an elisp function, and have to deal with users trying to call it from different contexts - the `fork' call for detaching needs to happen before some of the initialization is run (although after my 2008-09-28 change it might be possible to push it later), and also before .emacs is run and before the server is started.
