The last claimant. The kernel seeds the acpi-tables node, so it sits in the
same boot snapshot the manager already scans to find the PCI host bridge —
there was never a bootstrap problem, only a lookup nobody had written. The
manager claims it and names it in the spawn; the service stops claiming.
Every driver in the system now receives its hardware rather than taking it.
Two failures on the way, both mine. addDriver puts the device id in argv[1],
and the acpi service read argv[1] as a self-verify device-count floor — so
handed device 7 it decided it was in test mode, printed "acpi-parse: ok",
and never reported a device. The test argument is now floor:N, which a bare
id cannot be mistaken for.
And acpi-parse spawns the service directly rather than through the manager,
so nothing handed it the node. That test now claims and transfers it exactly
as the manager does, which is the right shape: the test plays the manager's
role instead of the service reaching for hardware.
device_claim now has two callers left: the manager, which is the acquirer
and should have it, and the display service's GOP path. That is recorded as
question 10 — the framebuffer is not a device, so the answer is likely that
it leaves the device table rather than being exempted from its rules.
Suite 118/118.
