9 * This test is used to check that the serial output of the firmware
10 * (that we provide for some machines) or some small mini-kernels that
11 * we provide here contains an expected string. Thus we check that the
12 * firmware/kernel still boots at least to a certain point and so we
13 * know that the machine is not completely broken.
