The company says its engineers write and maintain code in the kernel, in systemd and in image-building tools. If you run a Linux fleet, this changes what you check.

This system eschews traditional SSH access and package managers, instead relying on signed images and hardware-backed attestation (TPM or CPU attestation) to ensure machines adhere to their declared configurations.
