That's weird (though unrelated). I have not problem debugging
server-start with edebug.

AFAICS, if you start two Emacsen and both try to open the same local
socket, the error should be expected. You must somehow arrange for
them to have a different value of `server-name'.

I don't see it as a big problem, because obviously setting
EMACS_SERVER_FILE to ~/.emacs.d/server/server in your .profile is
trivial. However, if you really do feel that emacsclient should
default to TCP sockets if the server-file exists, please do comment it
on the developer's list; or I'll bring the issue, if you don't usually
read the list.

I can: having two Emacs servers around, one to connect from the local
machine (with Unix sockets) and the other for remote connections. Unix
sockets are inherently more secure (there's no sniffing around, at
least from the network); perhaps you don't want to have the same info
available in both. Remember that a simple:

 emacsclient --eval "(buffer-list)"

can reveal information, and

 emacsclient --eval "(let (kill-emacs-hook kill-emacs-functions) (kill-emacs))"

(or a more sophisticated variant) finish a session...
