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

Hi Guix!

I was recently updating my certbot definition to use a manual DNS
challenge, and I found using the Let's Encrypt staging server along with
the --dry-run option to be really useful. Especially given it can take a
few attempts to correctly build your own hooks.

So I've added the option to set dry-run? in the certificate
configuration, let me know what you think!  I've also included a couple
of patches in the series for minor fixes, removing a now deprecated flag
and a small fix in the docs.

Thanks,
Pierre

Just FYI, we are in "string freeze" until Guix 1.2.1 is released. This
means no changes to the manual or other translatable parts of Guix until
then.
