bug#55515: 29.0.50; Cannot restart a named daemon/create two named dameons

[Visuwesh]

When trying to create two named daemons, Emacs get stuck.  The problem
is also exhibited when I close a named daemon and try to recreate it as
in,

    % emacs -Q --daemon --socket-name=a
    Starting Emacs daemon.
    % pkill emacs
    % emacs -Q --daemon --socket-name=a
    Starting Emacs daemon.
    ...

I don't get the prompt back after recreating the daemon.  If I use a
different socket-name, the same problem is exhibited.

There are no problems if I don't give the socket-name however.

I don't see any sockets in /tmp or in $XDG_RUNTIME_DIR/emacs.  If I try
to remove $XDG_RUNTIME_DIR/emacs and start the daemon, Emacs still gets
stuck.

Why are you using "--socket-name=NAME" when starting the daemon?  That
option is for emacsclient; the daemon should be invoked with the
"--daemon-NAME" option instead.

Indeed, thanks for clarifying.  This is a case of a cockpit error.
Shame on me for not reading the manual carefully.  This bug can be
closed, thanks.

Thanks, closing.
