I could not figure out where this comes from.  As I mentioned it is not
in my store, yet (only) "guix system init" seems to look for it.

It is indeed quite surprising.  Especially since "type -P guix-register"
returns "/run/current-system/profile/sbin/guix-register" which links to
"/gnu/store/b5hfsdq8yzcqfvikfhm0gk95xa5pfwgy-guix-0.14.0-7.33988f9/sbin/guix-register"
and "type -P guix" returns "/run/current-system/profile/bin/guix" which links to
"/gnu/store/b5hfsdq8yzcqfvikfhm0gk95xa5pfwgy-guix-0.14.0-7.33988f9/bin/guix"
(for both my user and root).

It did not (I ran "guix pull" as user and as root last Friday,
2018-02-02).  And now after running "guix pull" again (as both user and
root) ~root/.config/guix/latest and ~/.config/guix/latest point to
/gnu/store/a565qard9xc0f0mg0vlbsrn419qgwfp9-guix-latest.

Unfortunately "sudo guix pull" and "guix pull" did not help either.
The error persists even after running
"guix system reconfigure /etc/config.scm" and rebooting.
