I modified the script to run the following commands as root:

```
guix package -i glibc-utf8-locales
systemctl restart guix-daemon
```

The script was already doing this.

When I run guix, it still produces the same locale messages:

```
$ guix package -I
guile: warning: failed to install locale
hint: Consider installing the `glibc-utf8-locales' or `glibc-locales' package
and defining `GUIX_LOCPATH', along these lines:

     guix package -i glibc-utf8-locales
          export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale"

See the "Application Setup" section in the manual, for more info.

glibc-utf8-locales      2.29    out     /gnu/store/n79cf8bvy3k96gjk1rf18d36w40lkwlr-glibc-utf8-locales-2.29
```

The --fallback option works.  Thank you for the suggestion.
