Saluton!  ;-)

Hmm, right.

But strangely enough:

--8<---------------cut here---------------start------------->8---
$ du -ms /var/run/current-system/sw/lib/locale/locale-archive
77      /var/run/current-system/sw/lib/locale/locale-archive

$ LOCALE_ARCHIVE=/var/run/current-system/sw/lib/locale/locale-archive locale -a
C
POSIX
--8<---------------cut here---------------end--------------->8---

And:

--8<---------------cut here---------------start------------->8---
$ guile
Guile Scheme interpreter 0.5 on Guile 1.9.0

Enter `,help' for help.
scheme@(guile-user)> (setlocale LC_ALL "ru_RU")
$1 = "ru_RU"
scheme@(guile-user)> (setlocale LC_ALL "fr_BE")
$2 = "fr_BE"
scheme@(guile-user)> (setlocale LC_ALL "ca_ES")
$3 = "ca_ES"
--8<---------------cut here---------------end--------------->8---

which basically shows that setlocale(3) succeeds with all these locales
that locale(1) doesn't even see.

What am I missing?

I agree (but I think it should still be easy to disable it).

Thanks,
