Im planning on doing a 2 cluster node dns/dhcp server without shared storage and a single print server on a third server. I was wondering if I am on the right track for the partitioning schemes, and would love to have some advice if I am not.

All three of these servers have a 136gb raid 5 and 4gb ram.

200mb boot
36gb EVMS
2gb swap
20gb sys_linux ext3
36gb Extended Partition
5gb /tmp ext3
10gb /var ext3
64gb freespace for nss volumes if I need them

I know there are 6 ways from sunday to configure your partitions, I would like to do this once and not have to look back again. Thanks in advance.
