On this tangent, I recently added a TEST_OUTPUT_DIRECTORY line to my config.mak which points into a tmpfs mount. Keeping all of the test repositories in RAM makes the tests significantly faster for me and works nicely when you have the patches in jk/test-output (without those patches the individual tests work but the reporting of aggregate results doesn't). -- 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
