    - Set memorylocked limit to 8Mb for default login class.
      This prevents unprivileged users to lock too much memory.
    - Set memorylocked limit to 64Mb for daemon login class.
      Some daemons such as amd(8) and watchdogd(8) calls mlockall(2) on
      startup, they are run from init(8) wich uses daemon login class.
    - Set memorylocked limit to unlimited for root login class.
