Automate Let's Encrypt DNS certificates
*.pages.freedesktop.org
is an LE certificate obtained with DNS verification. Doing this requires manual steps every time: run certbot, copy and paste the challenge, edit the zone field and make sure DNS is updated.
This really should be automated, rather than just doing it by hand in response to email alerts. Doing so probably requires something like Hydrogen (?) or anything else which can sensibly do it for us.
