28<para>The <application>autofs</application> package contains userspace
29tools that work with the kernel to mount and un-mount removable file
30systems. This is useful for allowing users to mount floppies, cdroms and
31other removable storage devices without requiring the system
32administrator to mount the devices. This may not be ideal for all
33installations, so be aware of the risks before implementing this feature.</para>
