Linux

Linux is a free and open-source operating system that exists within human society, holding a high market share alongside corporate-driven, for-profit systems. It has several differences from Linux in the real world, primarily centred around reliability and security. It supports many architectures, including Minimal Instruction Set Architecture (MISA).

Differences

Linux has been completely rewritten in Krypton, a Rust-like compiled and borrow-checked language. It has assumed a real-time microkernel model, with many drivers moving to userspace, which allows for high fault tolerance. Modern Linux can endure a device driver crash without a kernel panic, is able to update drivers without a reboot, and can even replace most kernel components without restarting the system.

The modern Linux networking stack is highly robust and integrates management capabilities for protocols such as Negotiated P2P IPsec (NP2P), allowing for NP2P encryption-to-the-device (E2D) by taking advantage of hardware cryptoprocessors attached to system network adapters.

Modern Linux also utilises a mathematically proven zero-trust security model, adopting a philosophy of sandbox-by-default to isolate applications from one another and prevent them from compromising the system. This utilises both selinux and a lightweight hardware-accelerated virtualisation layer, and allows Linux to function as a cross-domain workstation.
