I wonder if split-index does not work as intended. Because if it does, you should rarely need to write that such big index files (or is this 30mb the small part and the base index is even bigger?). But I agree with Torsten that we should make this configurable, preferably via config file, if not we can still move this define back in Makefile, overridable using config.mak -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
