I would like to have it on record that I completely agree with the points Chris (and Janne) made.

Absolutely agree with Janne about containers. We use the Centos 9 Stream
RPMs and have no plans whatever to move to cephadm
containers/orchestration. (Many reasons, but that's a different discussion).

What matters to us is:

  * properly tested packaging for the supported distributions,
    especially the Category A ones (this is becoming more problematic,
    especially in the python area)
  * properly tested functionality
  * prompt fixing of serious bugs, especially in the latest production
    version (we haven't even been able to move to squid yet because of
    the balancer pg-iteration bug). I'd love to see all Ceph systems
    being able to move easily to the supported releases (n, n-1) so that
    so much time isn't wasted on problems with obsolete releases.

Some of the new things in tentacle sound great, but we need to
concentrate on the current basics first. Timescales for the new features
are a much more minor consideration for us.

Ceph is a fantastic product. Let's keep it that way.

Chris
