At one point, I was considering to serialize just enough data to add
these in the initramfs-tools (and/or systemd) as Debian specific
patches to start supporting these measurements.
And have a distro patch in systemd to read these measurements from a
separately serialized file on boot-up.

Also, there are bootloader measurements, that I think we do not
receive either from grub.
