I consider these to be orthogonal. You need multiple install locations to let package.el manage additions in site-lisp, and also (maybe -- there are some questions here) the load-path for packages which are included with Emacs but also released separately. So suppose Emacs starts up and sees, say, 3 versions of gnus: one included in Emacs, one in site-lisp, and one in ~/.emacs.d/elpa/. Which one should be activated? Right now the obvious answer would be the newest one -- but Stefan wants to let the user pick a specific one. So, I think we'll need a bit of additional metadata about this. Tom
