AFAIK (G_ ...) cannot be used from within a G-exp. However, you could do: #~(begin ... (format #t #$(G_ "Starting services...~%"))) but that would make "shepherd.conf" depend on the locale that was active when "guix home ..." (*) was run, which may or may not be acceptable. (*) not sure what the exact command is. Alternatively, it might be possible to build the .mo from the .po translations and use bindtextdomain from the G-exp, in which case the G_ should be usable from the G-exp. Greetings, Maxime.
