In our case, all locally built software is in a separate tree, so
reinstalling a machine is almost never a problem; the locally built
software is either out on a backed-up NFS server, or its in a specific
directory separate from the OS distribution, which can easily be
backed up and restored. The configuration information is [almost] all
handled by cfengine, so in most cases nothing needs to be backed up on
the compute nodes at all, and rebuilding them is just a matter of PXE
booting them, hands-off.
