	Sets various kernel parameters at runtime.

	This plug-in is used for applying custom `sysctl` settings and should
	only be used to change system settings that are not covered by other
	*TuneD* plug-ins. If the settings are covered by other *TuneD* plug-ins,
	use those plug-ins instead.

	The syntax for this plug-in is
	`_key_=_value_`, where
	`_key_` is the same as the key name provided by the
	`sysctl` utility.
