Jason, that's not really true.

Do a PXE boot, and do a complete re-install from the installation
server.


I've frequently re-installed slave nodes on a Linux cluster.
For instance, change the system hard drive. Bring the system up, it
installs.

Even nicer if you have remote power switches, or ILMI management cards
in a machine room.

In the Unix/Linux world there are projects like LCFG where you store the
profile of a system on a server  http://www.lcfg.org
Or the Quattor stuff from CERN  http://www.quattor.org
