Systemd does not perform --wsrep-recover on restart

Details

    Description

      The systemd scripts packaged with MariaDB execute mysqld directly. This in turn prevents the --wsrep-recover and --wsrep-start-position mechanism from kicking in, as this mechanism is only found in mysqld_safe.

      As a result, restarting a crashed mysqld via systemd will always cause SST to take place even if IST is available:
