I'm glad you figured it out :)

It is completely different: with "-Q", your .emacs file is not loaded at
all, and with "--no-site-file", only the emacs packages from the guix
profile are not autoloaded.  Isn't that what you wanted?

If you want to autoload emacs packages from a guix environment (or
similarly from any non-standard guix profile), you can do it like this:

(let ((guix-env (getenv "GUIX_ENVIRONMENT")))
  (when (and guix-env
 (require 'guix-emacs nil t))
(guix-emacs-autoload-packages guix-env)))

Sorry, I don't understand your use case (I think I just didn't read your
message carefully enough), but if you think there is something to be
done, please tell.

Thanks for the tip, it seems to be working perfectly so far!

Damn!  Been stuck on this issue for days and it's right after sending
the last e-mail that I realized that install.scm was not inside
GUIX_PACKAGE_PATH...

Problem solved.

Build image for USB with custom kernel and packages

[Pierre Neidhardt]

Starting from /gnu/system/install.scm, I can run

> guix system disk-image install.scm

and it works.

Now if I add a custom kernel and a custom package to install.scm:

(define-public my-linux
  (package
(inherit linux-libre)
(name "my-linux")
(source ...

(define-public 
  (package
(name "foo")
(version version)
(source ...)
(build-system trivial-build-system)
(arguments
 `(#:modules ((guix build utils))
   #:builder ...))
(home-page "")
(synopsis "Blah blah")
(description "More blah blah")
(license #f

And in the `operating-system` form:

(operating-system
(kernel my-linux)
;; Rest is untouched.

I have to use more modules for this to work:

  #:use-module (guix packages)
  #:use-module (guix download)
  #:use-module (guix git-download)
  #:use-module (guix build-system trivial)

This fails to run:

> guix system disk-image install.scm
guile: warning: failed to install locale
warning: failed to install locale: Invalid argument
guix system: error: failed to load 'install.scm': No such file or 
directory

Am I missing something or is it a bug?

Right, but that's not very different from -Q: I get no start-site at all
and thus none of the Guix-installed packages. What I am looking for is a
way to get the packages that I put into the profile from which I started
Emacs.

I suspect that this could only be done via some environment variable,
analogous $PATH and others. Emacs doesn't consult any such variable, and
it seems that Guix didn't introduce one either. At least I didn't find
any.

Is this a decision made for a good reason, or just something "to be
done"? I could image guix-emacs.el consult a Guix-specific "Emacs path"
for constructing the internal load-path.

Konrad.
