This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.
I am moving this to RHEL 5.7 because the updates it references will not make the 5.6 release, as noted in BZ 488499. https://bugzilla.redhat.com/show_bug.cgi?id=488499
*** Bug 572721 has been marked as a duplicate of this bug. ***
This bug remained open because of possible 5.7 updates referenced in BZ#488499. But that bug has now been closed as WONTFIX so I'm closing this as NOTABUG since the new proposed mount options to document are not going to be included, as per that bug. So there's no documentation bug to fix.
