my "/etc/systemd/system/guix-daemon.service" says:

```
# This is a "service unit file" for the systemd init system to launch
# 'guix-daemon'.  Drop it in /etc/systemd/system or similar to have
# 'guix-daemon' automatically started.

ExecStart=/var/guix/profiles/per-user/root/current-guix/bin/guix-daemon --build-users-group=guixbuild

my GUIX_LOCPATH equals:

```
/home/david/.guix-profile/lib/locale
```

inside inside that directory is a foilder named "2.29" and it contains what looks like every locale.

My entire "env" is the following:
