Hey John,

Yes it's fine, thanks for the updated serie! I pushed the first patch
and patches two and three squashed together.

Ok, thanks for explaining. I don't have much experience with BPF
either. For now we can work with a separate linux-libre, and will see
about merging it into the default, when we'll have more perspective.
I'll take more time to review patches 4 and 5. However, while trying
some of the examples packaged by BCC, I have the following error:
--8<---------------cut here---------------start------------->8---

I think an additional wrapping is necessary. Could you please have a
look? I'm also removing help-guix, and opening a proper guix-patches
ticket.
Thanks,
Mathieu
