The file *fstab* contains descriptive information about the filesystems the system can mount. *fstab* is only read by programs, and not written; it is the duty of the system administrator to properly create and maintain this file. The order of records in *fstab* is important because *fsck*(8), *mount*(8), and *umount*(8) sequentially iterate through *fstab* doing their thing.
+The file is not read by *mount*(8) only but often is used by many other tools and daemons, and proper functionality may require additional steps. For example, on systemd-based systems, it's recommended to use *systemctl daemon-reload* after *fstab* modification.
