In my case, I found these ARM boards practical for self-hosting,
and I think the unique properties of GNU Guix are making it very suitable for that
purpose. I have installed GNU Guix on a Cubietruck, so my examples below will be
about that board. However, you should be able to change the examples for your
own use case.
