Forgot to add, a lot of the messages that are displayed at boot aren't
coming from the kernel, but from other services on the system. Those don't
show up in dmesg, which is purely the kernel's log.
Other log mechanisms will show them, such as the 'journalctl' command, or
looking in places like /var/log/syslog.
