Friday check-in: what are you running on Rocky Linux?

Home lab? Production web stack? Something weird and experimental you're not sure how to describe? We want to hear about it.

Drop your setup in the comments. It's always fun to see how people are actually putting Rocky to work out in the world.

Happy Friday, everyone.
