Hi Ken,

In the Ceph Leadership Team meeting today we discussed dropping
support for older distros in our Reef release. CentOS 9 and Ubuntu
Jammy (22.04) have been out for a while. With recent changes in Ceph's
main branch, it will make it easier to minimally require CentOS 9 and
Ubuntu Jammy with Python 3.9+ and a newer GCC.

Practically for users, this means we'd stop building and shipping RPMs
for CentOS 8 and debs for Ubuntu Focal from download.ceph.com. We
would make this change for the "main" branch soon, and Reef would be
the first stable release with this change (early-to-mid 2023).

As usual we would continue to build the older distro's packages (eg
CentOS 8 and Focal packages) for Quincy and earlier.

We have not shipped CentOS 9 packages or Ubuntu Jammy for Quincy to
download.ceph.com yet, and we plan to do that soon.

We deploy Ceph from Proxmox (Debian) repos, but I upstream support would be nice, and I have a strong dev background too :)

I see that new minimum versions for R will be OK in order to support Debian 11, which is nice (Debian 12 seems could be released mid-2023).

I also see that with the proposed plan, Ubuntu  18.04 and 20.04 will have 2 supported versions each, with one overlaped between Ubuntu versions, which will ease upgrades.

The same or better applies for CentOS.

I know the effort required to support older distros, both due to older versions in toolchain/dependencies and also in testing/infraestructure/support/bugfixing work.

I think the proposal is good so that effort and resources can be used to get higher quality R.

Thanks a lot
