1. As far as I know, it's not possible to simply copy a working /dev tree.
These are special files which are generated with the mknod utility.  

2. Booting a computer is fairly complex.  Everything needs to be at a specific
location on the drive, needs to occupy the appropriate sectors - which vary in
precise size depending on the drive geometry as well as the partitioning.  And
everything needs to appropriately connected together.

3. dd copies at the bit level.  It's a low level utility.  And that's why it
works, while the high level rsync or cp utility will not.
