When signing up for mastohost with an existing domain I own (whatever.com) the signup process forced me to use a subdomain (something.whatever.com). I don’t currently have a website on that root domain, but I would like to one day. Do I really have to have a long three part domain? Is there a way around it or is this a limitation of mastodon/mastohost?
Be warned though since the user account is tied with the domain and the domain will tied with the secret, so whenever you have a problem with it, and destroy it without tootctl self destruct.
It can become funky, which means that the other instances that were federated with it cannot federated with the new one.
The command is documented here https://docs.joinmastodon.org/admin/tootctl/#self-destruct
