There is much good to say about using kickstart method than learning a
new approach like Clonezilla. I have not used kickstart since Centos
4.something, so I have no good notes and will have to dig again. But
this is pretty much a one-time clone and Clonezilla does not seem to set
up the partitioning info on the new drive so that would be one more
thing to learn.
So I take the anaconda-ks.cfg file, add stuff so it will boot off the
network and use the update repo as well as the base. Then rediscover the
command to run linux from a kickstart file on a diskette.
Piece of CAKE!
