Which is planned to be added upstream in hal - in a nutshell, what is
needed for auto configuration of hardware is some mechanism to store 
configuration data about physical and logical devices in a persistent 
manner [1] accessible through a unified interface [2]. Once you have
that, it's not really hard to replace existing or write new policy

Heh, actually one thing I like about udev is the fact that it made
a lot of *existing* bugs and hacks like inserting "sleep 2" visible.
Oh wait, Greg KH already explained this here


and in surrounding messages :-)


[1] : Including the ability to tie configuration to specific device
instances, e.g. if a physical devices lacks a serial number we need
to track the data by connection.

[2] : Meaning that we shouldn't have 1000 different configuration
files in various formats.  With a unified interface it becomes 
almost trivial to write a "real" device manager, e.g. hal-device-
manager just with real management, for example, "Select MAC 
Address", "Select Interface Name" or "Select Driver" buttons for 
configuring networking hardware. It's just a simple SetProperty()
method call over D-BUS.
