Just to report that I did a successful install on one of those
machines. Starting with a 0.14 guix as root

  guix pull

restarted daemon using the new one in /root/.config/current/bin/

switched to normal user using the guix pointed in that directory

  /gnu/store/47hhyj0l4nk4na09qx1b66sz1wvpx95i-guix-command pull

Next I could run 

  ~/.config/current/bin/guix ...

everything appeared hunky dory until I need to build a package

Again as root I did another guix pull. It instates the same daemon

  /root/.config/guix/current/bin/guix-daemon -> 
/gnu/store/sf84mb2y5vcykwq9fv02l2nipp34qng2-guix-daemon-0.15.0-3.3d43017/bin/guix-daemon

Now guix pull fails in $USER

  which guix
  /home/wrk/.config/guix/current/bin/guix

  guix pull

Can you think of a way of getting out of this loop? What am I doing wrong here?
