Claude, I think there are several ways to do this.  For instance, you
could specify a different init file when invoking emacs.
Alternatively, you can start the emacsserver with --eval.  Yet another
way is to test the value of an environment variable which you can
explicitly set prior to invoking emacs, or in my case, I just use
SESSION_MANAGER.  Here is a snippet from my .emacs:

(if (not (eq (getenv "SESSION_MANAGER") 'nil))
    (server-start)
  (message "emacs server started"))
