iXsystems understands everyone makes their own decision, based on their desire for new features or stability. After 3,000 BETA users plus our own testing we think RC1 is safe. However, users that have zero time or interest in going through a bug resolution process may decide to do as you recommend, especially if their system is important to their work or lives....even though iX is saying that a RC should be fine for home use. I think I'll wait for -RELEASE, if not -U1 or -U2.
We appreciate both the early adopters that help us find issues, and the late adopters that help us avoid issues. It's a Community that makes it all work well.
