| 36 | <para><application>HAL</application> is a hardware abstraction layer, which
|
|---|
| 37 | is a piece of software that provides a view of the various hardware
|
|---|
| 38 | attached to a system. In addition to this, <application>HAL</application>
|
|---|
| 39 | keeps detailed metadata for each piece of hardware and provides hooks such
|
|---|
| 40 | that system and desktop-level software can react to changes in the hardware
|
|---|
| 41 | configuration in order to maintain system policy.</para>
|
|---|
| 42 |
|
|---|
| 43 | <para>The most important goal of <application>HAL</application> is to
|
|---|
| 44 | provide plug-and-play facilities for UNIX-like desktops with focus on
|
|---|
| 45 | providing a rich and extensible description of device characteristics and
|
|---|
| 46 | features. One example of the functionality provided by
|
|---|
| 47 | <application>HAL</application> is when you plug in a USB storage device.
|
|---|
| 48 | <application>HAL</application> can automatically create an appropriate
|
|---|
| 49 | entry in the <filename>/etc/fstab</filename> file and create the

| 50 | corresponding mount point in
