overriden at runtime (not enabled yet, but it works). This will allow us to build Glibc with no or a minimal set of locales (which cuts 70 MB from the installed size of Glibc). The locales that the user actually needs can then be built separately and enabled by setting the environment variable LOCALE_ARCHIVE. For instance, on NixOS, we could set it to something like /var/run/current-system/locale-archive. For setuid applications, the variable is ignored. This is especially useful on 64-bit systems, because there we tend to have *two* copies of locale-archive (namely in the 32-bit and 64-bit builds of Glibc). Having only one copy allows at least 70 MB to be cut from the NixOS installation CD. svn path=/nixpkgs/branches/stdenv-updates/; revision=15150
