The Linux System Administration concepts, commands and tasks covered here apply to the Red Hat, Fedora, Ubuntu, Kubuntu, Edubuntu, Slackware, Debian, SUSE, openSUSE – and ALL other Linux distributions!
Benefits of Setting Up Linux Directories as Mount Points of Partitions
When a directory is a assigned as a mount point to a partition, the files in the directory (and its subdirectories) cannot exceed the size of the partition.
For example, when you install Linux, you can assign the /home directory to a partition with a fixed size. The maximum amount of space that can be taken up by directories and files in this partition can not exceed the size specified.
The benefit of this is that the user or users that have home directories below /home can’t fill the entire disk with program files and data files!
To protect from an attack on your system by a user on: your LAN (Local Area Network), your intranet (internal internet network) or on the internet, some directories are commonly assigned to their own partitions. This restricts the damage that can occur from a “denial of service” attack, where someone automatically creates files in these directories so that they become full. If the directory (partition) becomes full, the entire disk does not become full and the system can still function until these files are deleted.
The home directory (for user data files), the var directory (for variable length files) and other “publicly available” (over a network) directories are commonly assigned to their own partitions to restrict the damage from a denial of service attack.
