hal is the user for the Hardware Abstraction Layer.  The account doesn't
have a password (you can look directly in /etc/shadow to see) so nobody
can log in as it.  It handles automounting removable media (such as
CD-ROM's, usb keys, etc.) as well in the future of handling other
devices such as batteries and many other things.
