🐧 Linux Crash Course - The /etc/fstab file The /etc/fstab file serves as a reference for programs, telling them how to handle filesystems on the system. Programs like mount, umount, and fsck use this file to determine specific mount points, options, and settings for each filesystem. For example, when the system boots, mount reads /etc/fstab and mounts filesystems as specified. If you run mount -a manually, it re-reads /etc/fstab and attempts to mount any filesystems listed there. Similarly, fsck, the filesystem check tool, refers to /etc/fstab to identify filesystems that need verification on boot, helping maintain filesystem integrity. Each line in /etc/fstab describes a filesystem and specifies details about its mount point, mount options, and other settings.
