Though I can not answer OP's question, I have question of my own.

Is this really routine (often) task for Linux sysadmins? I used 
something like that to replicate cluster nodes in the past, but 
kickstart would be routine task for me. dump/restore sounds like routine 
from MS Windows world (I hear they "re-image" system if something goes 
wrong ;-)

Am I wrong? Do we in Linux world do this routinely?
