Let me stress one thing though: Fedora *has* *no* working SecureBoot
implementation. The initrd is not authenticated. It has no signatures,
nothing.

By disabling SecureBoot you effectively lose exactly nothing in terms
of security right now.

What good is a trusted boot loader or kernel if it then goes on
loading an initrd that is not authenticated, super easy to modify (I
mean, seriously, any idiot script kiddie can unpack a cpio, add some
shell script and pack it up again, replacing the original one) – and
it's the component that actually reads your FDE LUKS password.

I mean, let's not pretend unsigned drivers were a big issue for
security right now. They are now, we have much much much wider gaping
holes in our stack.
