Dear Ludo,

If I understand 'guix pull' correctly below should simply not be
possible, right? I mean, once you do a guix pull you have the latest
and the greatest and there should be no interference? Intriguingly
this does not happen on all my systems, just on 2 - notably my laptop
I am using in Southern France ;)

Pj.
