The creator of systemd wants to bring SecureBoot-enforced hardware attestation to Linux (0pointer.net)

The creator of systemd (Lennart Poettering) has recently created a new company dedicated to bringing hardware attestation to open source software.

What might this entail? A previous blog post could provide some clues:

So, let's see how I would build a desktop OS. The trust chain matters, from the boot loader all the way to the apps. This means all code that is run must be cryptographically validated before it is run. This is in fact where big distributions currently fail pretty badly. This is a fault of current Linux distributions though, not of SecureBoot in general.

If this technology is successful, the end result could be that we would see our Linux laptops one day being as locked down as an Iphone or Android device.

There are lots of others who are equally concerned about this possibility: https://news.ycombinator.com/item?id=46784572

AFAIK, the allowing the user to install and remove certificates is a x86_64 thing only, arm will happilly fuck you over, x86_64 UEFI implementations ARE REQUIRED TO add that feature to be spec compliant, this was a intentional decision by Intel and AMD to keep x86_64 open to new OS and not locked down to Windows which could one day be a sinking ship, so that x86_64 would not be at the mercy of Microsoft's success and attachment to the platform

I have seen some platforms locked to Microsoft first party keys only. They boiled the frog by starting with it being optional, able to enroll your own keys, and Microsoft signing third party bootloaders, but now there exists a Microsoft-only certificate regime that at least some vendors have selected, or at least made a selectable option. The pitch being that Windows shops that don't trust their users can be assured they aren't deviating from the blessed windows os their IT trusts.
