Hi Bruno,

Does glibc look for ‘locale.alias’ in $sysconfdir, or does it look for
it in $localstatedir?
To follow the “correct way” as you described it, glibc should look for
it in $sysconfdir by default.

That’d be impractical of course, and that’s not how Guix works
(/gnu/store is immutable).

Right now gettext in Guix ends up being compiled with:
-DLOCALE_ALIAS_PATH=\"\"
(Example build log at
<https://ci.guix.gnu.org/log/0yy8zmgvc6hy1pfc41gm1bi7nhj4aqf7-gettext-0.21>.)
What you propose is doable. However, how many distros provide
/etc/locale.alias? What happens when it’s missing?
We have to keep in mind that Guix can be used on top of any distro.
Thanks,
Ludo’.
