Daemon configuration
~~~~~~~~~~~~~~~~~~~~
When you run +{daemon-bin-name}+, it configures itself from, in this order:

. The INI configuration file +{system_lttng_conf}+, if any.

. The INI configuration file `$LTTNG_HOME/.lttng/lttng.conf`, if any.
+
`$LTTNG_HOME` defaults to `$HOME`.

. With the option:--config='PATH' option: the INI configuration file
  'PATH'.

. The command-line options.

Each step can override a previous configuration property.

In INI configuration files, the session daemon only reads the properties
under the +{daemon-ini-section}+ INI section. Each INI property is:

Key::
    The long name of a command-line option to set (see the
    ``<<options,OPTIONS>>'' section below).

Value::
    The selected command-line option accepts an argument:::
        Option argument (string).

    The selected command-line option is a switch:::
        `true`::::
        `yes`::::
        `on`::::
            Enable the option.

        `false`::::
        `no`::::
        `off`::::
            Disable the option.
