We finally updated SBCL from 2.5.8 to 2.6.4 in Guix.

Many new Guix users struggle to get the system installed with working WiFi. There are a couple things I've read about doing this, but I wasn't satisfied with any of the approaches I knew about, so I wrote my own. Having tried several ways of doing this, I think this is the simplest; all you need is an Android phone.
