Ideally, there won=E2=80=99t be much to do to switch to 2.2. :-) Guix itself builds with 2.2, albeit slowly at the moment. We=E2=80=99d nee= d to routinely use 2.1 to see if there other issues. Of all the dependencies of Guix, I think only Guile-SSH needs =E2=80=9Cport= ing=E2=80=9D to 2.2, but even that should not be too much work. So it=E2=80=99s mostly about ironing things out and making sure we can transition smoothly enough, rather than a development project of its own. Ludo=E2=80=99.
