I think this is telling me that 1 line is formated incorrectly and because of that the checksum does not match. I did a websearch for lfs-bootscripts-20130821 but none of the results yielded could improve anything. So what I am thinking I'll do is (because the only known reason) for the failure is the improper formatting I  think I'll just do the build and hope it is correct until it doesn't install.
