Hey,
Thanks for the v2!

I have this error when building the documentation:
--8<---------------cut here---------------start------------->8---
guix.texi:34841: `@end' expected `lisp', but saw `defvar'
--8<---------------cut here---------------end--------------->8---
> +
> +
> +
Kill that extra line
> +;;;
> +;;; powertop
> +;;;
> +;;; Calls `powertop --auto-tune' to reduce energy consumption.
> +
> +
That one too.
> + (description "Tune power-related kernel parameters to reduce energy consumption.")))
Wrap it to be under 78 characters.
Thanks,
Mathieu
