The simplest way of forcing this to happen would be by specifying a
custom format on the boot command line ("ima_template_fmt=") and
measuring buffer data (ima-buf), like the kexec boot command line.
measure func=KEXEC_CMDLINE template=ima-buf
where "template=ima-buf" isn't needed on kernels with commit
dea87d0889dd ("ima: select ima-buf template for buffer measurement") .
