Sounds all great. Thanks for adding this before people start complaining that we fill the kernel log with 'userspace crap'. I actually removed all syslog daemons from my systems, and use only 'dmesg' these days, and no log is stored on disk, I just don't need it. People ask since a while for an option to suppress the kernel's [...] timestamp from the 'dmesg' output. Maybe you can make them happy too. :) Thanks, Kay -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
