I think it is unfortunate how difficult it is to back up a working linux 
machine and restore it onto different hardware, given that the system 
really is very hardware independent.  But, detecting the hardware and 
mapping it to device drivers seems to be a black art hidden inside of 
anaconda and then the local hardware related settings are fairly 
hopelessly intertwined with application and user preferences in your 
backup copies.  I always thought that this would be a common enough 
problem that some distribution would address it, but so far it hasn't 
happened.
