What is the purpose of the /etc/fstab file in Linux?

The /etc/fstab file in Linux is essential for defining how filesystems are mounted during the system's boot process. This configuration file establishes the default settings for filesystems, including their mount point, filesystem type, options for mounting, and parameters to be used when the system initializes.

Each line in the fstab file corresponds to a specific filesystem or partition and contains multiple fields that describe details like the device to be mounted, its mount point (where it appears in the directory structure), and specific mount options that influence how the filesystem behaves (e.g., whether it is mounted as read-only or allows user read/write access). This automatic mounting mechanism helps streamline boot processes, ensuring that necessary filesystems are available right from the start without requiring manual intervention each time the system starts.

The other options mentioned do not accurately describe the role of the /etc/fstab file. For instance, user account information is typically found in files such as /etc/passwd, and system log settings are managed through configuration in files like /etc/rsyslog.conf. Similarly, user login attempts are recorded in log files, not in the fstab file. Understanding the specific role of /etc/fstab is crucial for system management and for ensuring that all filesystems are
