The entire reason people tried installing from an ISO (some acrobatics like, install from ISO in a Standalone or USB qube copy to cloned Debian Template) must have been because a Template cannot be connected to networking since this grants access to Dom0. But that option is discouraged and not currently possible with Kicksecure.
It appears as there is no safe way to accomplish this goal since a Standalone cannot be redefined as a Template in Dom0 terminal after has been created, correct?
