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