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

Can't say it's obvious how to change certificates on my motherboard. Just updated the BIOS and had to turn off SecureBoot so it could boot into my Linux install (MSI B450 Tomahawk Max).

Every bios I've used has 2 sets of certificates built in. The default one is the Microsoft production certificate and the Linux bootloader doesn't match. But their should be another certificate for open source systems that will work.
