[oe] initramfs howto?

Including /conf/machine/include/kexecboot.inc in the machine.conf we
obtain the result of having one extra kernel built in the same image.

EXTRA_IMAGEDEPENDS += "linux-kexecboot"

You can create your own recipe linux-kexecboot like and populate the
cpio.gz as you like. The a.m. image must be as small as possible, thus
kblic, no shell and no modules, just a custom binary as /init.

BTW it is even possible to concatenate the modules (at the end) of the
cpio, after creating it.
