dbus, hald, policykit

[Warren Block]

Given that HAL and friends are now pretty much standard for desktop 
environments, shouldn't the Handbook have some (FreeBSD-specific) basic 
material on them?  For starters:


Overview

   HAL is a Hardware Abstraction Layer that attempts to "Make Hardware
   Just Work." http://www.ometer.com/hardware.html

   PolicyKit is a framework for defining policy for HAL.

   D-Bus is a message bus system that allows applications to communicate
   with each other.

Enabling (in rc.conf)
   dbus_enable="YES"
   hald_enable="YES"
   polkitd_enable="YES"

Basic Configuration
   adding a user to the operator group
   how to enable/disable automounting of removable media
   changing mount options for removable media
   /usr/ports/sysutils/hal-device-manager

...and that's pretty much everything I know about it, so someone else 
would have to expand on this.
