Nixpkgs Pivots

We have a number of problems that currently require full rebuilds of nixpkgs:

• glibc needs to find third-party nss modules
• cacerts needs to contain custom CA's from enterprises
• tzdata just changed frequently
• locales

Interestingly, Nix's deep pinning of cacerts and tzdata gets in the way of Nix's promise of packages working over the long term in an archival sense:

A funky shell thingy that I've never seen before

So you're in posix sh and you want to do the equivalent of this in bash:

foo | tee >(bar) >(baz) >/dev/null

(Suppose that bar and baz don't produce output. Add redirections where needed if that's not the case.)
