Well, you want to use something similar to the head in the compute
nodes, and you want the head node install to have all the necessary
infrastructure. Technically, you could use a different install on each
the nodes, but it wouldn't be smart.

Building a pill for the compute nodes a la Scyld or Perseus seems like
the best compromise in terms of reducing the compute node operating
environment while maintaining a common software base.
