The optimal way, I guess, would be to have some cache file with the results of such feature tests, that would be created and then used till the build fails using its findings, which would trigger a new feature check round, followed by an automatic rebuild. That would be tricky because we would have to have an automated way of discovering if the build failed due to missing packages or if it failed due to some ordinary coding mistake. - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
