With --localstatedir=/nix/var/nix (see store.scm and config.scm).

Remember: to bootstrap things here, you’re using Nixpkgs.  Here it’s
Nixpkgs’s glibc that uses kernel.org Linux headers.

At this point, you don’t want to build Hello.  ;-)  Instead, you should
build the bootstrap binaries, as described in HACKING, that will allow
our distro to be self-contained.  Make sure to use ‘core-updates’ as a
starting point.

HTH,
Ludo’.
