[Nix-dev] Re: perl: warning: Setting locale failed.

[Lluís Batlle]

Since the stdenv merge, I think, you have to explicitly install your locales.
In nixos, you can add in your configuration:
  environment = {
    extraPackages = [ pkgs.glibcLocales ];
  }

Further then, the locale system expects the locale archive (where all
the locales are compiled) in the path pointed by the env var
LOCALE_ARCHIVE (Nix-only feature of glibc). In my .bashrc I have:
export LOCALE_ARCHIVE=/var/run/current-system/sw/lib/locale/locale-archive

Btw, I vote for adding that export line into the boot stage 2 script,
if the file exists. And I vote for having the glibcLocales package
installed *by default*.

Anyone against?
