I'm attempting to fix my GuixSD system by downloading Guix
0.12.0 Binary, extracting and running guix-daemon, then running `guix
pull` against that. The daemon runs ok, but `guix pull` is expecting
its dependencies to be at /gnu, when they're actually at
~/Downloads/gnu. Any suggestions?

$ sudo
Downloads/gnu/store/gj2i5xs7nm80mwrb139pa8iqfccw08zz-guix-0.12.0/bin/guix-daemon
--build-users-group guixbuild --substitute-urls
