Then we could mention just @code{libgit2} in the footnote.  It is an
implementation detail, but one perhaps worth mentioning in this context
(otherwise a user could wonder "what does ~/.gitconfig have to do with
Guix?").

My point was that Guix alone couldn't care less about ~/.gitconfig, so
it seems confusing to me to mention it in relation to Guix.  It's really
a libgit2/git-specific thing, so should be mentioned somewhere, in my
opinion.

But now that you've pointed at our current style elsewhere, I guess your
original version is fine.  The good part about it is that by avoiding to
mention implementation details such as libgit2, it makes it less likely
that text will go stale as Guix evolves.

I've now applied the original, untouched.
