FYI, I added the following vectors:

        # kernel services that need to override task security
        class kernel_service
        {
                use_as_override
                create_files_as
        }

The first allows:

        avc_has_perm(daemon_tsec->sid, nominated_sid,
                     SECCLASS_KERNEL_SERVICE,
                     KERNEL_SERVICE__USE_AS_OVERRIDE,
                     NULL);

And the second something like:

        avc_has_perm(tsec->sid, inode->sid,
                     SECCLASS_KERNEL_SERVICE,
                     KERNEL_SERVICE__CREATE_FILES_AS,
                     NULL);

Rather than specifically dedicating them to the cache, I made them general.
