Lennart Poettering, Christian Brauner founded a new company

Two open‑source heavyweights just dropped a bombshell. Lennart Poettering (the guy behind systemd) and Linux file‑system boss Christian Brauner unveiled a new venture, Amutable, promising “verifiable integrity” from build to boot to runtime—translation: your computer only runs what’s proven trustworthy. Sounds neat… until the comments section lit up like a server rack.

The top vibe? Suspicious optimism. One commenter wondered if Poettering has quietly left Microsoft, while another fired the line of the day: worry about a “privacy nightmare” if “who controls the keys” isn’t crystal clear. That’s the core drama—trust, but with whose keys? Meanwhile, Amutable’s CEO, Chris Kühl, literally appears in the thread saying he’s “happy to answer questions,” which only made folks hungrier for specifics. “What’s the first thing you’ll tackle?” demanded one. Another asked in plain English: Who is this for—security or reproducibility?

Techies also spiraled into a debate over what “immutable” and “atomic” even mean for operating systems, then immediately noticed the name pun: Amutable launching a business about not changing things. Cue memes about “integrity, but make it fashion.” Details are thin, the team is stacked (ex‑Kinvolk, Pantheon, and more), and the pitch is bold. The crowd is split between “finally, trustworthy Linux for real” and “cool idea, but don’t lock the world behind someone’s keys.” Popcorn secured, keys… not so much.
