Means, the bootloader passes dk1 as the boot device.
But the code only checks "ld", "sd" and "wd" devices:
if (device_is_a(dev, "ld") || device_is_a(dev, "sd") ||
device_is_a(dev, "wd"))
fdt_detect_root_device(dev);
wedges are skipped, but even if a "dk" device would be checked, then:
if (of_hasprop(chosen, "netbsd,gpt-guid")) {
const struct uuid *guid =
fdtbus_get_prop(chosen, "netbsd,gpt-guid", &len);
if (guid != NULL && len == 16)
booted_device = dev;
return;
}
this matches anything.
In this case, the first "ld", "sd" or "wd" device matches as soon
as a netbsd,gpt-guid is passed by the bootloader.
