Reviewing system logs
In addition to kernel messages, many other boot-time messages will be logged using the syslog system. Such messages will be found in the system logfiles such as /var/log/messages. For example, dmesg displays information on your network adapter when it was initialized. However, the configuration and status of that adapter is logged in /var/log/messages as a result of the network startup. When examining and debugging boot activity on your system, you need to review both kinds of information. syslogd, its configuration, and logfile examination are covered in Chapter 16.
