That looks like the right direction, since running "guix pull -l" starts 
by saying

   Migrating profile generations to '/var/guix/profiles/per-user/root'...

Unfortunately, its next statement is just as magic but less pleasant:

Backtrace:
           6 (primitive-load "/root/.config/guix/current/bin/guix")
In guix/ui.scm:
  1583:12  5 (run-guix-command _ . _)

In unknown file:

ERROR: In procedure raise:
Wrong type (expecting exact integer): #<condition 
&profile-not-found-error [profile: 
"/var/guix/profiles/per-user/root/current-guix"] 338b460>


This looks like an error in an error-raising procedure, something like  
a meta-error ;-)

Looking at

  ~# ls -l /var/guix/profiles/per-user/root/current-guix
   lrwxrwxrwx 1 root root 14 oct.  15 13:51 
/var/guix/profiles/per-user/root/current-guix -> current-4-link

yields  a link that is indeed missing. What I do have is 
current-guix-4-link, but not a plain current-4-link.

Konrad.
