Hello Burkhard. Yes you are right indeed. Currently I'm using an Archlinux based custom development OS Nautilus. For reef, I have to develop a new custom OS from scratch and revisit all of my dependencies. I had too many issues on my custom Archlinux OS development before and had to spend too much time fixing the issues. I won't do that again. I decided to use Ubuntu 22.04 with Reef. I've done customizations and tunings based on my dependencies, hardware and use case. Ceph OS recommendations: https://docs.ceph.com/en/reef/start/os-recommendations/ " A: Ceph provides packages and has done comprehensive tests on the software in them." - Best.
