[Beowulf] Dual Boot in Master and Client

I didn't look, but I suspect warewulf uses all the usual
open-source tools.

if warewulf uses pxelinux, you can much more nicely configure
particular nodes to boot with particular default configs,
including different kernels, windows, etc by providing per-node
pxelinux.conf/ files.

I suspect that cygwin and ssh could do this nicely.  but being 
the blunt-object sort of guy, I'd rather reset the windows machines 
remotely via IPMI-over-lan ;)
