  Sometimes persistent network card info gets stored in  
/etc/udev/rules.d/z25_persistent-net.rules.  Your copy operation
will copy the MAC-address-indexed entry for a device on the old 
system, and when the new system boots up, it will think that 
the old device name is taken, and will assign a new device name
for its network card.

  So, you might discover that the network interface that was eth0
when you did the base install will suddenly become eth1 when 
you boot the copied system.

  The work-around, of course, is to remove the about-to-be-wrong
entry from that file after doing the copy.
