The directory commonly used in Linux systems to store log files is /var/log. This directory serves a crucial role in the system’s architecture because it is specifically designated for variable data that is expected to change often, which includes logs generated by the operating system and applications.

The /var/log directory contains a variety of log files that provide valuable information about system events, application operations, security authorization attempts, and more. Common log files you might find in this directory include syslog, messages, and specific logs for services like Apache and MySQL. System administrators frequently monitor these logs for troubleshooting and system auditing.

The other directories mentioned, such as /etc, /root, and /lib, have different purposes. For example, /etc holds configuration files, /root is the home directory for the root user, and /lib contains essential shared libraries and kernel modules. Thus, they do not serve the same purpose as /var/log when it comes to logging activities on a Linux system.
