Hello Konrad,

This was fixed in a subsequent commit:

  https://git.savannah.gnu.org/cgit/guix.git/commit/?id=3D8036b0942b8902214=
7aaf9cd9940988fdbcc19ef

To work around it, you can pull from an older generation, along these
lines:

  ~/.config/guix/current-42-link/bin/guix pull

(This will work because this older guix won=E2=80=99t attempt to move your
generations to /var/guix/profiles, so it allows you to =E2=80=9Cjump over=
=E2=80=9D the
bug.)

Let me know how it goes!

It=E2=80=99s terrible that a function like this that looks trivial has been
causing so much trouble.  Sorry about that.  :-/
