I’m trying to setup my Yubikey as an additional way to unlock my root LUKS volume as described in this post.
However, the system fails to boot as it immediately fails to decrypt the volume and I have to use the
rd.luks.crypttab=0 kernel command line option to make it ask for the password again. It looks like something is missing in the dracut image, but I can’t figure what it is. Anyone has experience with this kind of setup?
