 package.el does not initialize when emacs is launched with -q. This is
 somewhat problematic, since packages in the "core" dir should probably
 always be loaded. Unfortunately package.el is either initialized or

 that if files were moved from the "lisp" directory to the "package"

+*** Investigations
+
+package-initialize is the main issue here. It needs to run even with
+emacs -q, *but* only to load packages in core. At the same time it
+should not record that emacs has been initied, since running
+package-initialize again needs to load files in ~/.emacs.d/elpa.

+If non-nil, packages are activated after reading the init file

+Even if the value is nil, you can type \\[package-initialize] to
