OP, I took a cursory run through of the site. Looks good. Could really have potential for those just dipping their toes in the self hosting pool. I haven’t tested the ISO created tho. One thing, Tailscale client id & secret. I’m not sure I would want to disclose that on an unknown website, because of privacy issues. I understand why you included it, but it seems like an brief explanation as to how to do that manually, once the ISO is deployed, for those who might have some of the same reservations. Perhaps I overlooked that if it exists. Otherwise it looks like it would be a great introductory to self hosting.

Onward and upward.
