[CentOS] cloning a server

We use Kickstart. 

You can build a customised Kisckstart script to install anything you
want. Just put custom config files accessible off a web server, and you
can just copy those over as part of the setup. Or package them up into
your own RPMs and run your own repo. In fact, if you're doing several
of these, it's probably recommended to run your own repo with the base
and updates for speed and bandwidth savings.

You can have kickststart run a "yum update" so each box will have the
latest updates as at install time.

Your boot CD or flash stick can auto-boot the kickstart files, so all
you have to do is insert the media and turn the box on. Once it's done,
all you have to do is reboot and you're ready to go.
