Matthrew, perhaps you could clarify whether this will be tied to MAC
security.  Based on the kexec thread, I'm under the impression that is
not the intention, or at least not for kexec.  As root isn't trusted,
neither is the boot command line, nor any policy that is loaded by root,
including those for MAC.

thanks,

Mimi
