>Description:
	Update the tuning(7) manual page in order to reflect the use of bsdlalbel(8) instead of
	disklabel(8) ; and remove the note about the "new experimental feature" via the hw.ata.tags
	tunable which seems not longer exists.
>How-To-Repeat:
	At the prompt:
	 $ man 7 tuning
	And read... :)
>Fix:
	Here is a quick patch for the corresponding manual page source:

 The type of tuning you do depends heavily on where your system begins to
 bottleneck as load increases.
