Again, you get the same problem if you do:
emacs -Q -nw -f server-start --eval "(require 'ediff)"
emacsclient -c
M-x ediff
and you have a problem if you do
emacs -Q -f server-start --eval "(require 'ediff)"
emacsclient -t
M-x ediff

Not really, this is not a problem with --daemon, it's a problem in the
ediff implementation that it evaluates ediff-window-setup-function at
load time. This is not appropriate anymore now when you can have both
X11 and tty frames in the same emacs session.
