* Boot boots the target kernel based on information provided * in the "launcher" section of policy file. * * Summary of steps: * - extracts the kernel, initrd and cmdline from the "launcher" section of policy file. * - measures the kernel and initrd file into the tpmDev (tpm device). * - mounts the disks where the kernel and initrd file are located. * - uses kexec to boot into the target kernel. * returns error * - if measurement of kernel and initrd fails * - if mount fails * - if kexec fails
