  • Adding file systems

  • Mounting file systems

Some drives are connected (mounted) automatically into the file system. For example, a CD might be mounted on /media/cdrom. If the drive isn't mounted automatically, it is up to an administrator to create a mount point in the file system and then connect the disk to that point.

  • Swap space for Linux

  • Other file system types (perhaps containing other bootable operating systems) ...
