Sounds like kernel mode DRM or some similarly unwanted bullshit.

It's probably built on systemd's Secure Boot + immutability support. As said above, it's about who controls the keys. It's either building your own castle or having to live with the Ultimate TiVo. We'll see.

We all know who controls the keys. It's the first party who puts their hands on the device.

As the immediate responder to this comment, I claim to be the next guy. I love systemd.

I don't mind SystemD.

Just to make it clear - on Android you don't have the keys. Even with avb_custom_key you can't modify many partitions.

So LP is or has left Microsoft ? >We are building cryptographically verifiable integrity into Linux systems I wonder what that means ? It could be a good thing, but I tend to think it could be a privacy nightmare depending on who controls the keys.

The events includes a conference title "Remote Attestation of Imutable Operating Systems built on systemd", which is a bit of a clue.

I'm sure this company is more focused on the enterprise angle, but I wonder if the buildout of support for remote attestation could eventually resolve the Linux gaming vs. anti-cheat stalemate. At least for those willing to use a "blessed" kernel provided by Valve or whoever.

Can someone smarter than myself describe immutability versus atomicity in regards to current operating systems on the market?

Immutability means you can't touch or change some parts of the system without great effort (e.g. macOS SIP).

Atomicity means you can track every change, and every change is so small that it affects only one thing and can be traced, replayed or rolled back. Like it's going from A to B and being able to return back to A (or going to B again) in a determinate manner.

Really excited to a company investing into immutable and cryptographically verifiable systems. Two questions really:

1. How will the company make money? (You have probably been asked that a million times :).)

2. Similar to the sibling: what are the first bits that you are going to work on.

At any rate, super cool and very nice that you are based in EU/Germany/Berlin!
