The chosen language should affect the locale in the generated
config.scm, does it not?  If the locale in config.scm is correct, then
even if Guix has no translation at least the installed system will
have translations e.g. for GNOME and I believe this issue can be
closed.  Just the installer messages remain untranslated English for
now.

It should be possible to press Exit on the next installer steps to
select a different locale.  But maybe this does not work because of
the issue with umount-cowstore others wrote about.
