Kernel standardizes Rust and post‑quantum auth

The Linux 7.0 release removes the 'experimental' label for Rust in-kernel code and adds ML‑DSA post‑quantum signatures for kernel module authentication while removing SHA‑1 signing. Together these are pragmatic steps: broadening a memory‑safe language's role in a critical OS and beginning a real cryptographic transition for kernel trust chains. — Shifts in kernel language policy and module‑auth cryptography affect driver ecosystems, supply‑chain security, and national/enterprise readiness for post‑quantum threats.

Both describe institutional adoption of Rust at foundational OS layers; Canonical moving coreutils (userland) to uutils in Rust continues the same trajectory as kernel‑level Rust work and signals an ecosystem shift from 'Rust in pockets' to default system stacks — the article names Canonical, the uutils project, and audit findings (Zellic, 113 issues, 44 CVEs) that concretely tie to supply‑chain and security governance concerns captured by the existing idea.
