Subject: bug#1700: 23.0.60; Please provide a way to know if --daemon is supported
Date: Thu, 25 Dec 2008 00:03:44 -0800 (PST)

Currently I have a script that tries to use --daemon, but if it is not
supported falls back on creating an ordinary (mtty, or nothing) Emacs
session.  The test it uses for this is:

    emacs --batch -q --no-site-file --daemon >/dev/null 2>&1

However after my last weekly upgrade, this test fails even when
--daemon is supported.  Please provide a way to test for --daemon
support that will fail immediately on Emacs 21 and 22 (rather than
just launching an ordinary Emacs), and will succeed immediately when
--daemon is supported.
