The tar-ball works a treat!! Simply download and tar -C / --lzip -xvf guix-tarball-0.8.1.1140.tar.lz export ~/.guix-profile/bin:$PATH
Add the build users, update the /gnu/store permissions and start the daemon and that is it (which could be covered by a simple shell script). This should work on ANY Linux, provided kernel and architecture are compatible. Very nice. GNU Guix out of a box. No more installation pain. The tar-ball should go in the standard download directory. I would name the tar ball with something 'binary', maybe add the supported Linux versions (3.x?) and the architecture in the name. Just to be complete. There may be other editions later. Pj.
