Discussion items:

• [Ivan] On the ALMA minor version (from here): "Each minor version reaches end of life when the new version is released". It can be a motivation to keep the RHEL 9.X version up to date.

• [Shawn] AGLT2 has an updated script for FasterData and is looking for feedback (see here). It has been tested with a single storage server and the idea is to use it for capability mini-challenge.
