(Wow - long thread...)

Here's my current take.  I have wondered for a little while whether or
not having /etc/* be the only place that packages can put code that
runs at startup is sufficient.  For packages that want to make sure
certain things happen no matter what, things that shouldn't be
considered user-configurable, /etc is arguably not the right place.

The only reason that I chose /etc initially was because I was trying
to follow emacs upstream behaviour as closely as possible, and they
put all the auto-loaded stuff in /etc.  However, that doesn't mean
that we couldn't also augment policy to add a
/usr/share/emacs/site-start.d/ where packages could put their
non-configurable code.  However, then there would be the question of
ordering -- what happens first -- offhand, I'd say that /usr/share
would run before /etc so that admins could override things.

However, even if share/site-start.d is a bad idea, it seems like any
package manager can get almost the same effect by putting their init
code in /usr/share/<packagename>/foo.el and then putting something
like this into /etc/emacs/site-start.d/50foo-package.el:

  # The following line will run the default package initialization
  (load "/usr/share/foo-package/foo.el")

or perhaps the more fine grained:

  # Admin: comment out the following lines if you want to override
  # these directives

  # site-wide loading (controlled by debconf lookups?)
  (load "/usr/share/foo-package/site-wide.el")

  # favorite frob color
  (load "/usr/share/foo-package/get-and-set-frob-color.el")
