Firstly, thanks for a very useful service.
I’ve set up letsencrypt using certbot-auto and configured for apache. In the first instance I messed up and tried to put everything into one vhosts file. I’ve manually sorted this and everything is fine.
I’ve automated my renewals using cron - and I’m guessing the process will simply renew the certificates. There will be no further updates to the apache config files now… Right?
