I do have full disk encryption /boot included.
Or do you want your kernels to be tampered with by anyone that gets
hands onto your computer?

It is a bit more complex, but not that much.
The main trick was to automatically bake an extra decryption key into
the kernel every time it's installed, so you don't need to put it in
twice. (Once for GRUB to find the kernel, second time for kernel to be
able to touch the FS)
