So even if new information was only appended to the existing line, the script could break. If any script needs something stable it should depend on information available through other sources like trace or proc or sysfs. Tools that use dmesg should adapt to whatever gets thrown at it and handle the output from whatever kernel versions the script supports. For instance, what happens to the script when console_level is set to 1? Requiring that no one can change a dmesg to add or improve the content for readability or intelligibility I think unreasonable. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
