Oh, and btw, we have both H/A clusters and heavy-duty scientific computing
clusters. The h/a's have not been any problem upgrading. We're very
cautious on the scientific compute clusters, only because when we went, I
think it was, from 5.x to 6.x, or there were mathematical inconsistencies
that *may* have been from glibc. Those seem to have been resolved, but
they push back until they can verify the results via regression test.
You *do* have a test system or cluster for them to regression test on,
right...?
