State-Changed-When: Thu Jan 25 06:12:21 UTC 2007
State-Changed-Why: 
In CURRENT, "mount -u -o snapshot" does not remove the "acls"
mount option on an existing mount.  However, the behavior
described in this PR still exists in RELENG_6.
There has been a lot of refactoring of the mount code in
CURRENT, and not all of these fixes have made it to RELENG_6.
