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.
