Perhaps this is overkill, one simplification would be to assume
that the binary patches are only for systems installed from official ISOs
and so the binary update will take you from (say) 1.10.1 to 1.10.2 and will
complain if the file being patched does not have the expected intial
checksum. The principle being that a user is either in release plus binary
updates world or in build from source world but not in both.
