Agreed. > Chatty deamons are evil (or devils?). :-) But daemons which fork before detecting if there's an error somewhere and hence don't report such errors are even more evil. >> That means that detaching needs indeed to be done late if we want to do >> it right.

I can't tell yet whether Romain's patch does the right thing: do errors in .emacs get properly reported to stdout? >> What happens to messages resulting from executing .emacs in solution nb >> 2 are they sent to stdout or are they silently dropped? > deamon's stdin/stdout/stderr go to /dev/null. That's mostly OK, but not before the .emacs (and --eval) get processed. >> PS: Currently "emacs --daemon" doesn't do anything for me: it >> immediately (as in "I've never seen Emacs start or stop so fast") >> returns with no output and no remaining process. > How about "emacs -Q --daemon" ?
