We also use Debian.  We also use a heterogenous cluster (since our  
workload is embarrassingly parallel and the individual jobs are mostly  
single threaded, this doesn't really matter).

We use FAI for installation, since our nodes are not diskless, rsyslog  
for logging to a central log server, which is running Splunk.  We use  
cfengine 2 for configuration management.

We don't have diskless nodes, so the /var problem doesn't exist for us.

Regards,

Tim
