IMHO the MAC is an exception to this.
Since it's supposed to be hardcoded to the board it's inappropriate for the OS 
to be dynamically assigning it.
Currently we set the MAC from the protected flash of U-Boot into our 
Coldfire's fec before starting the OS(which is not necessarily Linux).
The boards can then be appropriatly shipped to customers with pre-programmed 
MAC addresses identifying the module, independent of the OS.

I realize this discussion centers around an ARM, however, so there may be 
hardware weirdness I don't know about that prevents this type of approach.
