Ooh, I see.  To work around an issue in our glibc 2.23 package (that I
forgot to fix in 2.24), whereby glibc does not look for locale data in
/run/current-system/locale, commit
ab3a64507a792e4da0527b423fbc28f8768e736a sets GUIX_LOCPATH in
/etc/environment.

However, that doesn’t help with daemons, because those do not honor that
file.

I suppose the untested patch below would work around it.  Could you try
and report back?  (Will require a reboot or testing with ‘guix system
vm’.)

Thanks,
Ludo’.
