Hi ludo,

I provided a reproducible case with how i arrive at this "weird" state in
a previous email.
But to answer your question, this is the difference after just invoking 
'guix pull'.

$ sdiff -s <(docker exec -i guix-test-1.0.1 sh <<<"namei 
/root/.config/guix/current") <(docker exec -i guix-test-latest sh <<<"namei 
/root/.config/guix/current")
 l current -> /var/guix/profiles/per-user/root/current-guix    |         l 
current -> /var/guix/profiles/default/current-guix
   d per-user                                                                   
    |      d default
   d root                                                     <
     l current-guix-1-link -> /gnu/store/rrhs9c8k0vbpirqplfzh  |             l 
current-guix-1-link -> /gnu/store/ls30zsp76w3nxkggkpb1
       d rrhs9c8k0vbpirqplfzh2bf1xczr3zan-profile                    |         
d ls30zsp76w3nxkggkpb1s6sdj5v2zzfl-profile

I don't know from where this 'default' come ^^

Regards,
