My preferred method is with a 100% vmware cluster. That is, I have a
"head node" image that I load up with RH9 (or whatever), unpack OSCAR,
etc. Then I snapshot the image.
I also have 2 additional vmware OSCAR nodes that are essentially blank --
I just let them be fully overwritten every time I do an install (i.e., I
don't intend to keep any information on those nodes from test to test).
Then I do an OSCAR install on the head [vmware] node. Once I have
completed it (either by premature failure or complete success), I save any
changes that I had to make to the package off to a real machine (i.e., scp
it off somewhere) and then revert to the vmware snapshot. Then I can
start the whole process again, but with a pristine copy of the OS --
guaranteed to be untainted by my previous OSCAR test.
Does that make sense?
