Nope. It looks to me [1] that, whilst booting, kernel messages are = written to that file in one batch after syslogd has been fired up. = Timestamps of those messages are all showing the very same second. Linux' dmesg has such a feature [2] I am looking for: | -d, --show-delta | | Display the timestamp and the time delta spent between | messages. If used together with =E2=80=94notimee then = only the time | delta without the timestamp is printed. Regards, Michael [1] is that correct? [2] http://man7.org/linux/man-pages/man1/dmesg.1.html=
