I recently tried adding a FIDO2-Device as an unlocking method to the LUKS2 partition containing my Fedora install. When trying to do this, I stumbled upon the here edited man files detailing how to do this. I however could not unlock my partition with my FIDO2-Device after editing /etc/crypttab and rebooting. As I found out after a while, I needed to regenerate / update my currently running / used initramfs (https://unix.stackexchange.com/a/705809). This would have most likely solved itself for me with the next kernel update install (as far as I understand). So I propose changing the files edited here to recommend or at least inform the user about this.
