What stays is one rule: a gate (compat, roms, lockdown, firmware,
logind), the release's report, the metric a workspace waits for
(ssh-first), and one tool per layer that says why it moved
(firmware-stages, initcalls, waits, page-cache).

  • boot:bench timed the serial console's prompt, which nothing a
    workspace waits for; boot:ssh-first replaces it in the instructions
    for a kernel, toolchain or mkosi bump. Its shared harness - variants,
    bootOnce, editOverlay, which the report runs - stays, as
    harness_test.go.
  • boot:trace, boot:userspace and boot:systemd: one boot's console, the
    gap before journald and systemd's journal timeline; boot:waits
    answers what they did.
  • boot:ssh-load: it concluded nothing is shipped for a loaded guest.
