//! ★ Lane G10 (2026-10-21): **Gunnar's media ask the SHARED hot-plug and wall-clock rows.**
//!
//! PCI hot-plug (35290f29, beside the runtime probe b247bf64) and the paravirt wall clock
//! (50c3e69) were written here first. Both lists now live in edda
//! `nornir_build_thing::kernel_requires`, so holger's installer media ask the same kernel the
//! same thing (holger declared no hot-plug, and a runtime grow on such a kernel answers 511).
//! One writer: this recipe keeps no copy of its own.
