Boot messages


I am getting a kernel panic with one particular kernel when I boot up, can somebody tell me how to record the panic message that comes up on the screen, dmesg does not hold.

Then I can post the message and ask questions

Tim

Edit /etc/default/bootlogd and change BOOTLOGD_ENABLE=No to BOOTLOGD_ENABLE=Yes. After a boot, you'll have the file /var/log/boot containing your boot messages. Older boots will probably get rolled over into boot.0. boot.1.gz, boot.2.gz, etc. as time goes on. But since you're getting a kernel panic, you might not see anything here. It would depend on where in the boot process the panic occurs. Hopefully you're panicing AFTER bootlogd has been started up! (I'm sure you probably are, so hopefully bootlogd will help)

p.s. - I don't know why bootlogd is not enabled by default. It sure seems like a useful thing to have. It's not like it takes up a ton of disk space to log this stuff.

Now, if somebody can tell me how to log SHUTDOWN messages ... I'm all ears. I haven't been able to figure that one out yet.
