I think the way to approach this is a blanket statement like:

Generally speaking, Ceph should work on any modern Linux distribution. 
In practice, we build packages for and test on a select set of common
distributions.

Starting with Octopus, we recommend deployments consume Ceph via a
container image instead of packages.  The container itself is based on
CentOS 8.  The container is generally consumed by either Rook.io or the
ceph-daemon tool.  In the later case, the OS requirements are relaxed, ...

Specifically, we build packages for:

...

We test on:

...

Something along those lines?

By the time of octopus release, I belive this will be:

Build
- CentOS 8 (x86_64)
- Ubuntu 18.04 (x86_64)
- Ubuntu 18.04 (aarch64)  (I think?)

Test
- centos 7.6 (containerized ceph only)
- centos 8.0
- ubuntu 18.04

We need to pin this down pretty soon.  Much of this is piled up behind
the py3 conversion, which is oh-so-close...
