>Description:
	It appears there are some pieces in RELENG_7 which still contain
	references to DTrace.  These pieces were added ~20 months ago, which
	would've been when -CURRENT was essentially 7.0-RELEASE.  I believe
	DTrace was "planned" for RELENG_7 at that time, but as we all know
	it didn't make it.  So I'm guessing someone simply forgot to remove
	the pieces:

		src/etc/mtree/BSD.usr.dist
		src/share/man/man7/hier.7

	The mtree results in users on RELENG_7 (present-day) having a
	directory called /usr/lib/dtrace that serves no purpose.

	hier(7) mentions this directory as well.

	n/a

	Remove applicable lines?  :-)

Responsible-Changed-By: gavin 
Responsible-Changed-When: Mon Apr 28 19:14:51 UTC 2008 
Responsible-Changed-Why:  
jb, can you have a look at this?  It looks like some bits of 
dtrace were never removed when it was taken back out of FreeBSD 
last time, so have found their way into RELENG_7

State-Changed-From-To: open->closed 
State-Changed-By: gavin 
State-Changed-When: Tue Apr 29 08:14:32 UTC 2008 
State-Changed-Why:  
Close this, there are plans to MFC DTrace, and removing these references just 
to re-add them will only cause unnecessary repo-churn, especially given the 
physical directory will now exist on disk anyway.  From jb: 

I'm not sure that I'd call this a bug. :-) 

The directory is still applicable to DTrace when it gets MFC'd. The design in 
current allows it to drop directly into RELENG_7 at some point. There is 
strong interest from vendors of FreeBSD based systems for DTrace support in 
both RELENG_7 and RELENG_6. 

The references /could/ be removed now without breaking anything, but they wil 
just need to be added back again later.
