Methods for modifying user configuration parameters

There are two methods to modify user configuration parameters:
  1. Edit the user configuration files and modify configuration parameters.
  2. Issue the dmctl command to modify configuration parameters when
    is running.
    Command-modified parameters are not persistent, which means that the modifications will be forgotten when
    is shut down and restarted. Every time that
    starts up, it sets its configurations in accordance to the parameter values in the user (and other) configuration files.
