Well, Chris Fanning has already given a good solution via Xen, but we used two different methods. At first times, we used to have two cheap servers with identical installations. Everytime we made an update on one server we did it in the other one too. It's very easy, but it isn't fast nor error-free. Actual solution in our case at EjerciciosResueltos use Subversion. Everything but the homes are under version control. Of course, that does NOT mean that every file is under version control, since files in, say, /usr/bin are controlled by the distro's package control system, and files in, say, /var/log must be machine-specific to allow us to get usage info, problems detectionand such. But it IS important to use svn to keep control of the installed packages. We used a nightly cron task to update the machine from the repository, and to update every configuration from SVN.
