Did you change your SelectType to cons_tres? How did it go?

We need to do the same change on one of our clusters. I have done a few
tests on a tiny test cluster which so far indicates that changing works
even with jobs running, but a configuration change with even a small
risk of purging the job list makes me a little nervous.
