func (l *Launcher) Boot() error

Boot boots the target kernel based on information provided in the "launcher" section of the policy file.

Summary of steps: - extract the kernel, initrd and cmdline from the "launcher" section of policy file. - measure the kernel and initrd file into the tpmDev (tpm device). - mount the disks where the kernel and initrd file are located. - kexec to boot into the target kernel.

returns error - if measurement of kernel and initrd fails - if mount fails - if kexec fails

func (*Launcher) MeasureInitrd

func (l *Launcher) MeasureInitrd() error

MeasureInitrd hashes the initrd and extends the measurement into a TPM PCR.

func (*Launcher) MeasureKernel

func (l *Launcher) MeasureKernel() error

MeasureKernel hashes the kernel and extends the measurement into a TPM PCR.
