[de.NBI Cloud Bielefeld - Production] Updated base images

17.02.2023 - 10:48
Dear de.NBI Cloud Bielefeld users, we have updated our pre-configured images based on Ubuntu LTS (18.04, 20.04, and 22.04) and Debian (10 and 11). All new images have a slightly different default behavior (see Change Log), but are still able to run on other cloud sites without any further modifications. Change Log: - Disable ipv4 TCP timestamps - Increase Read-Ahead-Cache to increase read performance for attached volumes. Previous images with the suffix (2022-10-14) are deactivated. On behalf of the de.NBI cloud Bielefeld team, Jan Krüger
