Subject: [PATCH] Make a root single user nix install possible

Taken from this issue https://github.com/NixOS/nix/issues/1559

This is only so that the script will succeed when running in docker
containers without systemd (can't use multi-user) and that have root as
the default user, a shockingly common practice
