The mount package contains the mount, umount, swapon and swapoff
programs. Accessible files on your system are arranged in one big
tree or hierarchy. These files can be spread out over several
devices. The mount command attaches a filesystem on some device to
your system's file tree. The umount command detaches a filesystem
from the tree. Swapon and swapoff, respectively, specify and disable
devices and files for paging and swapping.
