.The new `sshd_allow_restart` variable enables the `sshd` service to be restarted when needed Before this update, the `sshd` RHEL system role was not restarting the `sshd` service on a managed node when required. As a consequence, some changes related to configuration files from the`/etc/sysconfig/` directory and environment files were not applied. To fix the problem, the `sshd_allow_restart` (boolean, defaults to `true`) variable has been introduced to restart the `sshd` service on the managed node when necessary. As a result, the `sshd` RHEL system role now correctly applies all changes and ensures the `sshd` service actually uses those changes.
