Something I have noticed just now with the new "guix pull", but which
also happens with regular profiles through "guix package": Sometimes
(always?) unchanged profiles are created with a new number.
For instance, here is the result of three "guix pull" in my profile:
$ guix pull -l

The third generation is identical to the second one and should not have
been created.
