[Nix-dev] awesome locale issues

[Lluís Batlle i Rossell]

nixpkgs' glibc will look at LOCALE_ARCHIVE env var for its locale-archive.
You can install a locale archive instantiating "glibc-locales" by nix. Then set
that environment variable pointing to it.

locale-archives are incompatible between glibc versions, and ubuntu in fact is
providing none of them, iirc.

Regards,
Lluís.
