I am using certbot to pre-generate certificates for sub domains.
I observed that if I provide a different configuration directory to certbot for each subdomain the files under accounts directory for each subdomain i.e. meta.json, private_key.json and regr.json are different.
This seems innocuous to me since I was able to renew certificates for each subdomain. I use the same email address (email@example.com) when requesting certificate for each of the subdomains.
However I want to make sure I don’t violate any terms by associating numerous accounts with this one email.
Also off topic: What would be the maximum time LE takes to issue/renew a certificate?
