Thanks, installed.
[Message part 3 (message/rfc822, inline)]
1. emacs -Q --fg-daemon=/nonexistent/dir/sock
2. Emacs prints "Starting Emacs daemon." and sits in foreground.
3. emacsclient -c -s /nonexistent/dir/sock
4. emacsclient prints and exits:
emacsclient: can't find socket; have you started the server?
emacsclient: To start the server in Emacs, type "M-x server-start".
emacsclient: error accessing socket "/nonexistent/dir/sock"
This is because in step 1, the server actually failed to start, but
Emacs did not log that at all. In fact, it's impossible to access the
Emacs started in 1 now, since it's not actually running a server and it
has no frames.
The same thing happens with --bg-daemon, although it's slightly more
obvious that something is wrong in that case, because --bg-daemon is not
supposed to sit in foreground.
Emacs with --fg-daemon should instead print an error and exit if it
fails to start the server.
