- sd-stub: automatically pick up microcode from ESP (/loader/microcode/*)
and synthesize initrd from it, and measure it. Signing is not necessary, as
microcode does that on its own. Pass as first initrd to kernel.
- - systemd-creds should have a fallback logic that uses neither TPM nor the
- system key in /var for encryption and instead some fixed key. This should
- be opt in (since it provides no security properties) but be used by
- kernel-install when encrypting the creds it generates on systems that lack
- a TPM, so that we can have very similar codepaths on TPM and TPM-less
- systems. i.e. --with-key=tpm-graceful or so.
- sd-stub should measure the kernel/initrd/… into a separate PCR, so that we
have one PCR we can bind the encrypted creds to that is not effected by
anything else but what we drop in via kernel-install, i.e. by earlier EFI
