Opensuse Leap 15 will have 2.0.14, so I would be okay with it.

2.2 is not as easy as I thought it would be, to bring it to openSUSE
Leap. There are packages who still require guile 2.0 (see comments in
https://build.opensuse.org/request/show/568553). And the fact that only
a handful of packages need guile, makes it not really worthwhile for
distros to have two versions of guile present like we see it for python.

It would be nice to have guix in Debian, Ubuntu, SUSE land and Red Hat
land. I think that would enable far more people to use guix.

At the moment it's not easy to install guix from source without having
guix in place, at least on openSUSE. You need those guile modules
(guile-git, guile-bytestructures) who comes with almost no build
documentation. And then you have to fiddle together guile with the right
versions...

We struggle a lot with bootstrapping rust, go, java etc, so we should
make sure that "bootstrapping" guix (install from source) is easy or at
least doable.
