Who would want to use a rolling release distribution for a (production) server? Sounds like a pretty terrible choice, to be quite honest.
I used Arch on my laptop (primarily used for development) for several years. It mostly worked great and I always had access to the newest whatever with a minimum of hassle. I don't have many complaints, but occasionally after an update something critical would stop working.
I'm on Solus now and, so far, it's been pretty great. :-)
Rolling release is great for technically competent users to install on their workstations, but why would you ever want a rolling release on a production server?
