After upgrading Jenkins from version 2.319.2 to 2.332.2 whatever changes (ex: port , keystore path) I do in /etc/sysconfig/ is not being applied. Please help
Jenkins 2.332.1 switched Jenkins from using System V init to use systemd with its Linux package installers for Debian, Ubuntu, Red Hat, Alma, openSUSE, Rocky, and more. The LTS Upgrade Guide describes that transition and how to adapt your environment to the transition.
