Only want to have ONE disk in the system, and it needs to be in the Windows
box to support the the data acq function. Dual boot of the laptop isn't a
viable option for a variety of reasons.
As far as the cluster goes, one could still have one of the nodes as "head
node" and serving as the portal through which all communication
flows. However, the challenge seems to be in serving the boot images. I
suppose that headnode could be flash disk'ed and run the dhcp server, with
the actual images being served from the laptop. All that would need to be
on the headnode would be the dhcp configuration file and the PXE
hmm.. starts to look like local boot media of some sort on at least one of
the nodes is going to be necessary.
