Right, this patch set avoids incrementing the CPIO magic number and
the resulting changes required (eg. increasing the timestamp field
size), by including a file with the security xattrs in the CPIO.  In
either case, including the security xattrs in the initramfs header or
as a separate file, the initramfs, itself, needs to be signed.
