No, no, it is expected; I meant ":/etc/emacs" is the default value,
sorry for the confusion.

No, there is no need to fix load-path; on GuixSD it should work
out-of-the-box; it doesn't work currently because there is a bug
introduced several days ago (see below).

Thanks for confirmation!

Well, you can do it as a temporary workaround, but we'll fix it soon (I
mean the system profile will also be inspected for emacs packages), so
it will not be necessary in the closest future.

Yes, I mean it's not a problem on your side, but it's bug in GuixSD. I
think we should change this value from ":/etc/emacs" to "/etc/emacs:".
The problem with the current EMACSLOADPATH is that "/etc/emacs" value is
appended to 'load-path' variable, but it should be prepended to it, so
that the proper "site-lisp.el" will be found.
Sorry, this bug was introduced recently and you are the first who faced
it :-)
Right now I can't check it, but I think if you start emacs like this:
EMACSLOADPATH=/etc/emacs: emacs
you'll get "M-x guix-…" commands. Could you confirm?
So to recap, you found 2 issues:
1. Emacs packages installed in a system profile are not automatically
added to 'load-path'.
2. With the current EMACSLOADPATH, a wrong "site-lisp.el" is loaded, so
"M-x guix-…" commands are not autoloaded.
Both are easy to fix, thanks again for reporting!
