+Compatibility with Podman Versions
+----------------------------------
+
+Podman and Ceph have different end-of-life strategies that
+might make it challenging to find compatible Podman and Ceph 
+versions
+
+Those versions are expected to work:

+changes in the near future:
+
+- RGW
+
+Cephadm support for the following features is still under development:
+
+- RGW-HA

-use in production and at scale.  We would like users to try cephadm,

-frequent updates and improvements over the first several bug fix
-releases of Octopus.

-
-- Monitors
-- Managers
-- OSDs
-- CephFS file systems
-- rbd-mirror
-- NFS
