Hi,

--8<---------------cut here---------------start------------->8---
$ guix shell --pure
guix shell: warning: no packages specified; creating an empty environment
guix shell: warning: no packages specified; creating an empty environment
--8<---------------cut here---------------end--------------->8---

That=E2=80=99s because: one is from =E2=80=99auto-detect-manifest=E2=80=99 =
in (guix scripts
shell):

  (if (or (not interactive?)
          disallow-implicit-load?
          (options-contain-payload? opts))
      opts
      (match (find-file-in-parent-directories '("manifest.scm" "guix.scm"))
        (#f
         (warning (G_ "no packages specified; creating an empty environment=
~%"))
         opts)

called by =E2=80=99parse-args=E2=80=99 called by the entry-point command =
=E2=80=99guix-sell=E2=80=99.

And another one is from =E2=80=99guix-environment*=E2=80=99 in (guix scripts
environment):

        (when (null? (manifest-entries manifest))
          (warning (G_ "no packages specified; creating an empty environmen=
t~%")))

called by the entry-point command =E2=80=99guix-shell=E2=80=99.

Well, since =E2=80=98guix environment=E2=80=99 is deprecated, I would sugge=
st to remove
the warning in =E2=80=99guix-environment*=E2=80=99.  It would improve the =
=E2=80=9Cpolish=E2=80=9D.

Cheers,
simon
