Can you install Guix (the OS) on just a single partition? I tried going through the graphical installer and mounting a single existing free partition as /. Thinking that all of Guix would then go on that partition. But the next step in the installer said ‘We are about to format your hard drive, is that OK?’. So I bailed out at that point… Presumably you don’t *have* to format the whole disk? – what’s the way to use just a single partition?
