Filesystem question (sort of newbie)

Let me recommend Warewulf (warewulf-cluster.org). It
boots the nodes using RH 7.3 (although it should work with
8 or but I haven't tested it), but it boots into a small Ram
Disk (about 70 megs depending upon what you need on the
nodes). It's very easy to setup, configure and use, plus you
don't need to install RH on each node. Warewulf will use
a hard disk in the nodes if available for swap and local scratch
space. However, it will also work with diskless nodes (although
you don't get swap or scratch space).
Warewulf will also take /home from the master node and
NFS mount it throughout the cluster. So you can install your
code on /home for all of the nodes.
