'Completely' is not possible, and I would not like it.

Think about the content of /proc, or hardware/kernel related messages in 
/var/log.

The only possibility (which I know) to fully sync a root / is, to run it 
as a guest in XEN or vserver. This means having DRBD and the cluster 
manager running in the host, and booting the guest at failover.

See

IMHO there should be a serious need for virtualization. Just syncing the 
installed packages and the configuration is _not_ a serious reason.
