Speaking of this, how does Nix ensure that `configure' scripts won't
discover things (programs, libraries, C include files, etc.) outside the
Nix store?

It seems that `configure' may need to run inside a chroot where only
`/nix/store/*' (and `/bin/sh') are visible.  Actually, rather than
`/nix/store/*', the chroot would need to have `~/.nix-profile' as `/',
with symlinks followed.  Plash [0] seems like a good tool to setup such
restricted name spaces.

Thanks,
Ludovic.
