Where Linux places the messages of boot?

Solution 1:

Most of the boot messages are put in a buffer, that you can access using the command dmesg. On most Linux distributions, that output is also stored in

/var/log/dmesg.log

That you can view with

tail -n 100 /var/log/dmesg.log

Solution 2:

Every exceptional entry during boot is placed in /var/log/syslog Could also be in /var/log/boot.msg
