Clonzilla probably uses the same underlying tools, plus ntfsclone as the
default option for ntfs partitions, but I think it has better network
support with options for multicast mass-cloning and the ability to
store/load the images over nfs/smb/sshfs as well as local storage. It
works fine as-is. I just wondered if anyone had done the same on a
centos-live distribution base. One thing that would be a great addition
would be if, after the image is restored to the disk, you could drop
into the equivalent of a rescue mode boot and be able to chroot to the
newly installed system without needed a reboot. But, I guess the NICs
might not be detected as the same devices when booted with different
kernels, initrd's or modprobe.conf files anyway.
