Game of Certs - e01 - the elusive Parent Domain

What would I give for a Sunday free of assumptions!

Yet again I've been humbled by relatively single tasks & lagunas of my memory.

sudo certbot certonly --agree-tos --email [email protected] --manual *.domain.com --preferred-challenges=dns

will work only for the wildcard domains, while:

sudo certbot certonly --agree-tos --email [email protected] --manual -d domain -d *.domain.com --preferred-challenges=dns

will work for both the parent domain and the subdomains!
