[Message part 1 (text/plain, inline)]

Hi Ludovic and Sergey,

the patch looks good to me. Thanks for adding the tests.

I would have expected #t, #f or a string as the value of
hetzner-configuration-ipv4 and hetzner-configuration-ipv6.

It's a pitty the null issue in guile-json has no comments yet.

I would say, let's merge it. The default behaviour right now is to
enable ipv4 and ipv6 and this patch does the same. Once the issue in
guile-json has been fixed we gain the ability to disable via #f, right?

Thanks, Roman.
