Someone in the Fedora community should have the answer. I have been testing on F37 before trying Dom0. Good thing. It looks like I will have to cycle though in and out of emergency shell a few times to find the right disk nomenclature for crypttab if there isnt some other missing step like forming sym links.
Until then, a psychic malevolent fire department could steal our Centuries strong passwords and frame our computers if we leave them unguarded at home our when they are out of our watchful eye. How do they do it? Must get help from Tailored Access Ops. I am interested in eventually getting measured boot like HEADS can. That is more parsimoniously useful to people who don’t know the FD. Otherwise, you could have someone mail your security key to you after you successfully pass totalitarian check points. You could parental control access to a computer also with security key LUKS lock. Anyway, cool thing to learn how to do. You could physically lock servers as well as remotely administer them with USB keys.
