emacs-overlay, site-lisp, package-directory-list

[permezel]

Hi, New to NixOs. Been trying to use the emacs-overlay to install emacs and install some elpa packages.
When I arrange for emacs-pgtk, emacs-30.0.50 is installed, but no site-lisp/elpa dir is made available.

There is an attempt to make site-lisp/elpa available:

package-directory-list
"/nix/store/rcvqqvkswpl9ph6ssv8i00vg5b0ps85l-emacs-pgtk-20230918.0/share/emacs/30.0.50/site-lisp/elpa"
"/nix/store/rcvqqvkswpl9ph6ssv8i00vg5b0ps85l-emacs-pgtk-20230918.0/share/emacs/site-lisp/elpa"

Neither of these directories exists. If I poke about in /nix/store I see there is a

/nix/store/r07c3ib9wwwpkgx2cpb3fk61wisgxxql-emacs-packages-deps:
total 0
0 dr-xr-xr-x 1 root root 272 Jan  1  1970 bin
0 dr-xr-xr-x 1 root root  24 Jan  1  1970 lib
0 dr-xr-xr-x 1 root root  10 Jan  1  1970 share

which would probably work if it was in the package-directory-list, as follows:

Here is the emacs-packages-deps which has what I believe I need:

It looks as if this should be the site-lisp. I was wondering where my default.el was being staged.

Every time I delete my ~/.config/emacs/elpa dir and re-start emacs, I just rebuild everything back into ~/.config/emacs/elpa and ignore the site-lisp/elpa ones, due to the package-directory-list not including the correct path.
