I know not many of you use Gentoo, but for those who do, I’ve put together an overlay filled with ebuilds (mainly version 1.3.0) of almost all the certbot DNS plugins:
app-crypt/certbot-dns-nsone is missing, because it’s already in the official Gentoo repository. It is however a little bit outdated. If someone would like me to include it anyway, but more recent, please ask.
Also, please comment if anyone has any or ask any question you have
